The word ''strenuous'' in Quran

Ragheb says '' this word means achieving ultimate purpose and object from aspects of time and place with of determined affairs''. It means ending in the following verses;
وَوَصَّيْنَا الْإِنسَانَ بِوَالِدَيْهِ إِحْسَانًا ۖ حَمَلَتْهُ أُمُّهُ كُرْهًا وَوَضَعَتْهُ كُرْهًا ۖ وَحَمْلُهُ وَفِصَالُهُ ثَلَاثُونَ شَهْرًا ۚ حَتَّىٰ إِذَا بَلَغَ أَشُدَّهُ وَبَلَغَ أَرْبَعِينَ سَنَةً قَالَ رَبِّ أَوْزِعْنِي أَنْ أَشْكُرَ نِعْمَتَكَ الَّتِي أَنْعَمْتَ عَلَيَّ وَعَلَىٰ وَالِدَيَّ وَأَنْ أَعْمَلَ صَالِحًا تَرْضَاهُ وَأَصْلِحْ لِي فِي ذُرِّيَّتِي ۖ إِنِّي تُبْتُ إِلَيْكَ وَإِنِّي مِنَ الْمُسْلِمِينَ
We have enjoined on man kindness to his parents: In pain did his mother bear him, and in pain did she give him birth. The carrying of the (child) to his weaning is (a period of) thirty months. At length, when he reaches the age of full strength and attains forty years, he says, "O my Lord! Grant me that I may be grateful for Thy favour which Thou has bestowed upon me, and upon both my parents, and that I may work righteousness such as Thou mayest approve; and be gracious to me in my issue. Truly have I turned to Thee and truly do I bow (to Thee) in Islam''.
إِنَّ الَّذِينَ يُجَادِلُونَ فِي آيَاتِ اللَّهِ بِغَيْرِ سُلْطَانٍ أَتَاهُمْ ۙ إِن فِي صُدُورِهِمْ إِلَّا كِبْرٌ مَّا هُم بِبَالِغِيهِ ۚ فَاسْتَعِذْ بِاللَّهِ ۖ إِنَّهُ هُوَ السَّمِيعُ الْبَصِيرُ
Those who dispute about the signs of Allah without any authority bestowed on them,- there is nothing in their breasts but (the quest of) greatness, which they shall never attain to: seek refuge, then, in Allah: It is He Who hears and sees (all things).
فَلَمَّا بَلَغَ مَعَهُ السَّعْيَ قَالَ يَا بُنَيَّ إِنِّي أَرَىٰ فِي الْمَنَامِ أَنِّي أَذْبَحُكَ فَانظُرْ مَاذَا تَرَىٰ ۚ قَالَ يَا أَبَتِ افْعَلْ مَا تُؤْمَرُ ۖ سَتَجِدُنِي إِن شَاءَ اللَّهُ مِنَ الصَّابِرِينَ
Then, when (the son) reached (the age of) (serious) work with him, he said: "O my son! I see in vision that I offer thee in sacrifice: Now see what is thy view!" (The son) said: "O my father! Do as thou art commanded: thou will find me, if Allah so wills one practising Patience and Constancy''.
وَقَالَ فِرْعَوْنُ يَا هَامَانُ ابْنِ لِي صَرْحًا لَّعَلِّي أَبْلُغُ الْأَسْبَابَ
Pharaoh said: "O Haman! Build me a lofty palace, that I may attain the ways and means''.
أَمْ لَكُمْ أَيْمَانٌ عَلَيْنَا بَالِغَةٌ إِلَىٰ يَوْمِ الْقِيَامَةِ ۙ إِنَّ لَكُمْ لَمَا تَحْكُمُونَ
Or have ye Covenants with Us to oath, reaching to the Day of Judgment, (providing) that ye shall have whatever ye shall demand?
It also means terminating in the following verses;
وَإِذَا طَلَّقْتُمُ النِّسَاءَ فَبَلَغْنَ أَجَلَهُنَّ فَأَمْسِكُوهُنَّ بِمَعْرُوفٍ أَوْ سَرِّحُوهُنَّ بِمَعْرُوفٍ ۚ وَلَا تُمْسِكُوهُنَّ ضِرَارًا لِّتَعْتَدُوا ۚ وَمَن يَفْعَلْ ذَٰلِكَ فَقَدْ ظَلَمَ نَفْسَهُ ۚ وَلَا تَتَّخِذُوا آيَاتِ اللَّهِ هُزُوًا ۚ وَاذْكُرُوا نِعْمَتَ اللَّهِ عَلَيْكُمْ وَمَا أَنزَلَ عَلَيْكُم مِّنَ الْكِتَابِ وَالْحِكْمَةِ يَعِظُكُم بِهِ ۚ وَاتَّقُوا اللَّهَ وَاعْلَمُوا أَنَّ اللَّهَ بِكُلِّ شَيْءٍ عَلِيمٌ
When ye divorce women, and they fulfil the term of their (´Iddat), either take them back on equitable terms or set them free on equitable terms; but do not take them back to injure them, (or) to take undue advantage; if any one does that; He wrongs his own soul. Do not treat Allah´s Signs as a jest, but solemnly rehearse Allah´s favours on you, and the fact that He sent down to you the Book and Wisdom, for your instruction. And fear Allah, and know that Allah is well acquainted with all things.
It also means that he or she has grown up in higher age, but it is not appropriate to say that he or she has become old;
قَالَ رَبِّ أَنَّىٰ يَكُونُ لِي غُلَامٌ وَقَدْ بَلَغَنِيَ الْكِبَرُ وَامْرَأَتِي عَاقِرٌ ۖ قَالَ كَذَٰلِكَ اللَّهُ يَفْعَلُ مَا يَشَاءُ
He said: "O my Lord! How shall I have son, seeing I am very old, and my wife is barren?" "Thus," was the answer, "Doth Allah accomplish what He willeth''.
It also means sufficiency;
قَالَ رَبِّ أَنَّىٰ يَكُونُ لِي غُلَامٌ وَكَانَتِ امْرَأَتِي عَاقِرًا وَقَدْ بَلَغْتُ مِنَ الْكِبَرِ عِتِيًّا
He said: "O my Lord! How shall I have a son, when my wife is barren and I have grown quite decrepit from old age?''
إِنَّ فِي هَٰذَا لَبَلَاغًا لِّقَوْمٍ عَابِدِينَ
Verily in this (Qur´an) is a Message for people who would (truly) worship Allah.
This word also means preaching in the following verses;
فَاصْبِرْ كَمَا صَبَرَ أُولُو الْعَزْمِ مِنَ الرُّسُلِ وَلَا تَسْتَعْجِل لَّهُمْ ۚ كَأَنَّهُمْ يَوْمَ يَرَوْنَ مَا يُوعَدُونَ لَمْ يَلْبَثُوا إِلَّا سَاعَةً مِّن نَّهَارٍ ۚ بَلَاغٌ ۚ فَهَلْ يُهْلَكُ إِلَّا الْقَوْمُ الْفَاسِقُونَ
Therefore patiently persevere, as did (all) messengers of inflexible purpose; and be in no haste about the (Unbelievers). On the Day that they see the (Punishment) promised them, (it will be) as if they had not tarried more than an hour in a single day. (Thine but) to proclaim the Message: but shall any be destroyed except those who transgress?
وَمَا عَلَيْنَا إِلَّا الْبَلَاغُ الْمُبِينُ
And our duty is only to proclaim the clear Message.
وَإِن مَّا نُرِيَنَّكَ بَعْضَ الَّذِي نَعِدُهُمْ أَوْ نَتَوَفَّيَنَّكَ فَإِنَّمَا عَلَيْكَ الْبَلَاغُ وَعَلَيْنَا الْحِسَابُ
Whether We shall show thee (within thy life-time) part of what we promised them or take to ourselves thy soul (before it is all accomplished),- thy duty is to make (the Message) reach them: it is our part to call them to account.
مَّا عَلَى الرَّسُولِ إِلَّا الْبَلَاغُ ۗ وَاللَّهُ يَعْلَمُ مَا تُبْدُونَ وَمَا تَكْتُمُونَ
The Messenger´s duty is but to proclaim (the message). But Allah knoweth all that ye reveal and ye conceal.
وَقَالَ الَّذِينَ أَشْرَكُوا لَوْ شَاءَ اللَّهُ مَا عَبَدْنَا مِن دُونِهِ مِن شَيْءٍ نَّحْنُ وَلَا آبَاؤُنَا وَلَا حَرَّمْنَا مِن دُونِهِ مِن شَيْءٍ ۚ كَذَٰلِكَ فَعَلَ الَّذِينَ مِن قَبْلِهِمْ ۚ فَهَلْ عَلَى الرُّسُلِ إِلَّا الْبَلَاغُ الْمُبِينُ
The worshippers of false gods say: "If Allah had so willed, we should not have worshipped aught but Him - neither we nor our fathers,- nor should we have prescribed prohibitions other than His." So did those who went before them. But what is the mission of messengers but to preach the Clear Message?
هَٰذَا بَلَاغٌ لِّلنَّاسِ وَلِيُنذَرُوا بِهِ وَلِيَعْلَمُوا أَنَّمَا هُوَ إِلَٰهٌ وَاحِدٌ وَلِيَذَّكَّرَ أُولُو الْأَلْبَابِ
Here is a Message for mankind: Let them take warning therefrom, and let them know that He is (no other than) One Allah: let men of understanding take heed.
It also means divine messages and Quran because Quran includes meanings that God has obliged to the prophet (peace of Allah be upon him and his descendants) so that he can transfer them to people. Quran also includes purposes that if a mature person achieves them, they will not be deviated and will not go awry and will achieve happiness in the afterlife. It also means remembering God because it reminds human tendency toward creator, thinking about future and prudence about existence and seen and unseen affairs.
In Quran, God has allowed his prophet to preach divine messages and orders him to annunciate mission of creator to persons as Quran states
يَا أَيُّهَا الرَّسُولُ بَلِّغْ مَا أُنزِلَ إِلَيْكَ مِن رَّبِّكَ ۖ وَإِن لَّمْ تَفْعَلْ فَمَا بَلَّغْتَ رِسَالَتَهُ ۚ وَاللَّهُ يَعْصِمُكَ مِنَ النَّاسِ ۗ إِنَّ اللَّهَ لَا يَهْدِي الْقَوْمَ الْكَافِرِينَ
O Messenger! proclaim the (message) which hath been sent to thee from thy Lord. If thou didst not, thou wouldst not have fulfilled and proclaimed His mission. And Allah will defend thee from men (who mean mischief). For Allah guideth not those who reject Faith.
Quran also states
يَا أَيُّهَا الْمُدَّثِّرُ
O thou wrapped up (in the mantle).
قُمْ فَأَنذِرْ
Arise and deliver thy warning.
وَأَنذِرْ عَشِيرَتَكَ الْأَقْرَبِينَ
And admonish thy nearest kinsmen.
فَاصْدَعْ بِمَا تُؤْمَرُ وَأَعْرِضْ عَنِ الْمُشْرِكِينَ
Therefore expound openly what thou art commanded, and turn away from those who join false gods with Allah.
It also means hitting and torturing and it devotes hypocrites;
أُولَٰئِكَ الَّذِينَ يَعْلَمُ اللَّهُ مَا فِي قُلُوبِهِمْ فَأَعْرِضْ عَنْهُمْ وَعِظْهُمْ وَقُل لَّهُمْ فِي أَنفُسِهِمْ قَوْلًا بَلِيغًا
Those men,-Allah knows what is in their hearts; so keep clear of them, but admonish them, and speak to them a word to reach their very souls. In fact, it can be understood from the above verse, hypocrites are persons that do stop hurting prophet and believers.
وَلَقَدْ جَاءَهُم مِّنَ الْأَنبَاءِ مَا فِيهِ مُزْدَجَرٌ
There have already come to them Recitals wherein there is (enough) to check (them).
أُولَٰئِكَ الَّذِينَ يَعْلَمُ اللَّهُ مَا فِي قُلُوبِهِمْ فَأَعْرِضْ عَنْهُمْ وَعِظْهُمْ وَقُل لَّهُمْ فِي أَنفُسِهِمْ قَوْلًا بَلِيغًا
Those men,-Allah knows what is in their hearts; so keep clear of them, but admonish them, and speak to them a word to reach their very souls.
أَلَمْ تَرَ إِلَى الَّذِينَ قِيلَ لَهُمْ كُفُّوا أَيْدِيَكُمْ وَأَقِيمُوا الصَّلَاةَ وَآتُوا الزَّكَاةَ فَلَمَّا كُتِبَ عَلَيْهِمُ الْقِتَالُ إِذَا فَرِيقٌ مِّنْهُمْ يَخْشَوْنَ النَّاسَ كَخَشْيَةِ اللَّهِ أَوْ أَشَدَّ خَشْيَةً ۚ وَقَالُوا رَبَّنَا لِمَ كَتَبْتَ عَلَيْنَا الْقِتَالَ لَوْلَا أَخَّرْتَنَا إِلَىٰ أَجَلٍ قَرِيبٍ ۗ قُلْ مَتَاعُ الدُّنْيَا قَلِيلٌ وَالْآخِرَةُ خَيْرٌ لِّمَنِ اتَّقَىٰ وَلَا تُظْلَمُونَ فَتِيلًا
Hast thou not turned Thy vision to those who were told to hold back their hands (from fight) but establish regular prayers and spend in regular charity? When (at length) the order for fighting was issued to them, behold! a section of them feared men as - or even more than - they should have feared Allah: They said: "Our Lord! Why hast Thou ordered us to fight? Wouldst Thou not Grant us respite to our (natural) term, near (enough)?" Say: "Short is the enjoyment of this world: the Hereafter is the best for those who do right: Never will ye be dealt with unjustly in the very least.
أَيْنَمَا تَكُونُوا يُدْرِككُّمُ الْمَوْتُ وَلَوْ كُنتُمْ فِي بُرُوجٍ مُّشَيَّدَةٍ ۗ وَإِن تُصِبْهُمْ حَسَنَةٌ يَقُولُوا هَٰذِهِ مِنْ عِندِ اللَّهِ ۖ وَإِن تُصِبْهُمْ سَيِّئَةٌ يَقُولُوا هَٰذِهِ مِنْ عِندِكَ ۚ قُلْ كُلٌّ مِّنْ عِندِ اللَّهِ ۖ فَمَالِ هَٰؤُلَاءِ الْقَوْمِ لَا يَكَادُونَ يَفْقَهُونَ حَدِيثًا
Wherever ye are, death will find you out, even if ye are in towers built up strong and high!" If some good befalls them, they say, "This is from Allah"; but if evil, they say, "This is from thee" (O Prophet). Say: "All things are from Allah." But what hath come to these people, that they fail to understand a single fact?
يَا أَيُّهَا الرَّسُولُ لَا يَحْزُنكَ الَّذِينَ يُسَارِعُونَ فِي الْكُفْرِ مِنَ الَّذِينَ قَالُوا آمَنَّا بِأَفْوَاهِهِمْ وَلَمْ تُؤْمِن قُلُوبُهُمْ ۛ وَمِنَ الَّذِينَ هَادُوا ۛ سَمَّاعُونَ لِلْكَذِبِ سَمَّاعُونَ لِقَوْمٍ آخَرِينَ لَمْ يَأْتُوكَ ۖ يُحَرِّفُونَ الْكَلِمَ مِن بَعْدِ مَوَاضِعِهِ ۖ يَقُولُونَ إِنْ أُوتِيتُمْ هَٰذَا فَخُذُوهُ وَإِن لَّمْ تُؤْتَوْهُ فَاحْذَرُوا ۚ وَمَن يُرِدِ اللَّهُ فِتْنَتَهُ فَلَن تَمْلِكَ لَهُ مِنَ اللَّهِ شَيْئًا ۚ أُولَٰئِكَ الَّذِينَ لَمْ يُرِدِ اللَّهُ أَن يُطَهِّرَ قُلُوبَهُمْ ۚ لَهُمْ فِي الدُّنْيَا خِزْيٌ ۖ وَلَهُمْ فِي الْآخِرَةِ عَذَابٌ عَظِيمٌ
O Messenger! let not those grieve thee, who race each other into unbelief: (whether it be) among those who say "We believe" with their lips but whose hearts have no faith; or it be among the Jews,- men who will listen to any lie,- will listen even to others who have never so much as come to thee. They change the words from their (right) times and places: they say, "If ye are given this, take it, but if not, beware!" If any one´s trial is intended by Allah, thou hast no authority in the least for him against Allah. For such - it is not Allah´s will to purify their hearts. For them there is disgrace in this world, and in the Hereafter a heavy punishment.
Rashid says '' eloquence means achieving purpose and meaning with few words''. Ragheb believes that eloquence is based on acquiring two things: expressing meaning and purpose and recognition of eloquent remarks and ineloquent ones.
Imam Ali (peace be upon him) defines this word '' it means looking at reasons and recognition of chances, giving up clear statements and tending irony''. Abu Helal narrates from Imam Ali (peace be upon him) '' this word means elucidating wrong affairs and finding out weak points''. Imam Ali (peace be upon him) said to his child, Imam Hasan (peace be upon him) '' eloquence means elucidating ambiguous wisdom and difficult science''.
