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 ٢٣١

أَجَلَهُنَّ ajalahunna · their (waiting) term

And when you divorce women and they have [nearly] fulfilled their term, either retain them according to acceptable terms or release them according to acceptable terms, and do not keep them, intending harm, to transgress [against them]. And whoever does that has certainly wronged himself. And do not take the verses of Allāh in jest. And remember the favor of Allāh upon you and what has been revealed to you of the Book [i.e., the Qur’ān] and wisdom [i.e., the Prophet's sunnah] by which He instructs you. And fear Allāh and know that Allāh is Knowing of all things. (Surah Al-Baqarah, 2:231)

وَإِذَا طَلَّقْتُمُ النِّسَاءَ فَبَلَغْنَ أَجَلَهُنَّ فَلَا تَعْضُلُوهُنَّ أَن يَنكِحْنَ أَزْوَاجَهُنَّ إِذَا تَرَاضَوْا بَيْنَهُم بِالْمَعْرُوفِ ذَٰلِكَ يُوعَظُ بِهِ مَن كَانَ مِنكُمْ يُؤْمِنُ بِاللَّهِ وَالْيَوْمِ الْآخِرِ ذَٰلِكُمْ أَزْكَىٰ لَكُمْ وَأَطْهَرُ وَاللَّهُ يَعْلَمُ وَأَنتُمْ لَا تَعْلَمُونَ ٢٣٢

أَجَلَهُنَّ ajalahunna · their (waiting) term

And when you divorce women and they have fulfilled their term, do not prevent them from remarrying their [former] husbands if they [i.e., all parties] agree among themselves on an acceptable basis. That is instructed to whoever of you believes in Allāh and the Last Day. That is better for you and purer, and Allāh knows and you know not. (Surah Al-Baqarah, 2:232)

وَيَوْمَ يَحْشُرُهُمْ جَمِيعًا يَا مَعْشَرَ الْجِنِّ قَدِ اسْتَكْثَرْتُم مِّنَ الْإِنسِ وَقَالَ أَوْلِيَاؤُهُم مِّنَ الْإِنسِ رَبَّنَا اسْتَمْتَعَ بَعْضُنَا بِبَعْضٍ وَبَلَغْنَا أَجَلَنَا الَّذِي أَجَّلْتَ لَنَا قَالَ النَّارُ مَثْوَاكُمْ خَالِدِينَ فِيهَا إِلَّا مَا شَاءَ اللَّهُ إِنَّ رَبَّكَ حَكِيمٌ عَلِيمٌ ١٢٨

أَجَّلْتَ ajjalta · You appointed

And [mention, O Muḥammad], the Day when He will gather them together [and say], "O company of jinn, you have [misled] many of mankind." And their allies among mankind will say, "Our Lord, some of us made use of others, and we have [now] reached our term which You appointed for us." He will say, "The Fire is your residence, wherein you will abide eternally, except for what Allāh wills. Indeed, your Lord is Wise and Knowing." (Surah Al-An'am, 6:128)

وَمَا كَانَ لِنَفْسٍ أَن تَمُوتَ إِلَّا بِإِذْنِ اللَّهِ كِتَابًا مُّؤَجَّلًا وَمَن يُرِدْ ثَوَابَ الدُّنْيَا نُؤْتِهِ مِنْهَا وَمَن يُرِدْ ثَوَابَ الْآخِرَةِ نُؤْتِهِ مِنْهَا وَسَنَجْزِي الشَّاكِرِينَ ١٤٥

مُّؤَجَّلًا mu-ajjalan · determined

And it is not [possible] for one to die except by permission of Allāh at a decree determined. And whoever desires the reward of this world - We will give him thereof; and whoever desires the reward of the Hereafter - We will give him thereof. And We will reward the grateful. (Surah Ali 'Imran, 3:145)

مِنْ أَجْلِ ذَٰلِكَ كَتَبْنَا عَلَىٰ بَنِي إِسْرَائِيلَ أَنَّهُ مَن قَتَلَ نَفْسًا بِغَيْرِ نَفْسٍ أَوْ فَسَادٍ فِي الْأَرْضِ فَكَأَنَّمَا قَتَلَ النَّاسَ جَمِيعًا وَمَنْ أَحْيَاهَا فَكَأَنَّمَا أَحْيَا النَّاسَ جَمِيعًا وَلَقَدْ جَاءَتْهُمْ رُسُلُنَا بِالْبَيِّنَاتِ ثُمَّ إِنَّ كَثِيرًا مِّنْهُم بَعْدَ ذَٰلِكَ فِي الْأَرْضِ لَمُسْرِفُونَ ٣٢

أَجْلِ ajli · time

Because of that, We decreed upon the Children of Israel that whoever kills a soul unless for a soul or for corruption [done] in the land - it is as if he had slain mankind entirely. And whoever saves one - it is as if he had saved mankind entirely. And Our messengers had certainly come to them with clear proofs. Then indeed many of them, [even] after that, throughout the land, were transgressors. (Surah Al-Ma'idah, 5:32)
