1. 2:226 لِّلَّذِينَ يُؤْلُونَ مِن نِّسَآئِهِمْ تَرَبُّصُ أَرْبَعَةِ أَشْهُرٍ فَإِن فَآءُو فَإِنَّ ٱللَّهَ غَفُورٌ رَّحِيمٌ

   Those who swear that they will not go in to their wives should wait four months; so if they go back, then Allah is surely Forgiving, Merciful.
   

2. 16:48 أَوَلَمْ يَرَوْا۟ إِلَىٰ مَا خَلَقَ ٱللَّهُ مِن شَىْءٍ يَتَفَيَّؤُا۟ ظِلَٰلُهُۥ عَنِ ٱلْيَمِينِ وَٱلشَّمَآئِلِ سُجَّدًا لِّلَّهِ وَهُمْ دَٰخِرُونَ

   Do they not consider every thing that Allah has created? Its (very) shadows return from right and left, making obeisance to Allah while they are in utter abasement.
   

3. 33:50 يَٰٓأَيُّهَا ٱلنَّبِىُّ إِنَّآ أَحْلَلْنَا لَكَ أَزْوَٰجَكَ ٱلَّٰتِىٓ ءَاتَيْتَ أُجُورَهُنَّ وَمَا مَلَكَتْ يَمِينُكَ مِمَّآ أَفَآءَ ٱللَّهُ عَلَيْكَ وَبَنَاتِ عَمِّكَ وَبَنَاتِ عَمَّٰتِكَ وَبَنَاتِ خَالِكَ وَبَنَاتِ خَٰلَٰتِكَ ٱلَّٰتِى هَاجَرْنَ مَعَكَ وَٱمْرَأَةً مُّؤْمِنَةً إِن وَهَبَتْ نَفْسَهَا لِلنَّبِىِّ إِنْ أَرَادَ ٱلنَّبِىُّ أَن يَسْتَنكِحَهَا خَالِصَةً لَّكَ مِن دُونِ ٱلْمُؤْمِنِينَ قَدْ عَلِمْنَا مَا فَرَضْنَا عَلَيْهِمْ فِىٓ أَزْوَٰجِهِمْ وَمَا مَلَكَتْ أَيْمَٰنُهُمْ لِكَيْلَا يَكُونَ عَلَيْكَ حَرَجٌ وَكَانَ ٱللَّهُ غَفُورًا رَّحِيمًا

   O Prophet! surely We have made lawful to you your wives whom you have given their dowries, and those whom your right hand possesses out of those whom Allah has given to you as prisoners of war, and the daughters of your paternal uncles and the daughters of your paternal aunts, and the daughters of your maternal uncles and the daughters of your maternal aunts who fled with you; and a believing woman if she gave herself to the Prophet, if the Prophet desired to marry her-- specially for you, not for the (rest of) believers; We know what We have ordained for them concerning their wives and those whom their right hands possess in order that no blame may attach to you; and Allah is Forgiving, Merciful.
   

4. 49:9 وَإِن طَآئِفَتَانِ مِنَ ٱلْمُؤْمِنِينَ ٱقْتَتَلُوا۟ فَأَصْلِحُوا۟ بَيْنَهُمَا فَإِنۢ بَغَتْ إِحْدَىٰهُمَا عَلَى ٱلْأُخْرَىٰ فَقَٰتِلُوا۟ ٱلَّتِى تَبْغِى حَتَّىٰ تَفِىٓءَ إِلَىٰٓ أَمْرِ ٱللَّهِ فَإِن فَآءَتْ فَأَصْلِحُوا۟ بَيْنَهُمَا بِٱلْعَدْلِ وَأَقْسِطُوٓا۟ إِنَّ ٱللَّهَ يُحِبُّ ٱلْمُقْسِطِينَ

   And if two parties of the believers quarrel, make peace between them; but if one of them acts wrongfully towards the other, fight that which acts wrongfully until it returns to Allah's command; then if it returns, make peace between them with justice and act equitably; surely Allah loves those who act equitably.
   

5. 59:6 وَمَآ أَفَآءَ ٱللَّهُ عَلَىٰ رَسُولِهِۦ مِنْهُمْ فَمَآ أَوْجَفْتُمْ عَلَيْهِ مِنْ خَيْلٍ وَلَا رِكَابٍ وَلَٰكِنَّ ٱللَّهَ يُسَلِّطُ رُسُلَهُۥ عَلَىٰ مَن يَشَآءُ وَٱللَّهُ عَلَىٰ كُلِّ شَىْءٍ قَدِيرٌ

   And whatever Allah restored to His Messenger from them you did not press forward against it any horse or a riding camel but Allah gives authority to His messengers against whom He pleases, and Allah has power over all things.
   

6. 59:7 مَّآ أَفَآءَ ٱللَّهُ عَلَىٰ رَسُولِهِۦ مِنْ أَهْلِ ٱلْقُرَىٰ فَلِلَّهِ وَلِلرَّسُولِ وَلِذِى ٱلْقُرْبَىٰ وَٱلْيَتَٰمَىٰ وَٱلْمَسَٰكِينِ وَٱبْنِ ٱلسَّبِيلِ كَىْ لَا يَكُونَ دُولَةًۢ بَيْنَ ٱلْأَغْنِيَآءِ مِنكُمْ وَمَآ ءَاتَىٰكُمُ ٱلرَّسُولُ فَخُذُوهُ وَمَا نَهَىٰكُمْ عَنْهُ فَٱنتَهُوا۟ وَٱتَّقُوا۟ ٱللَّهَ إِنَّ ٱللَّهَ شَدِيدُ ٱلْعِقَابِ

   Whatever Allah has restored to His Messenger from the people of the towns, it is for Allah and for the Messenger, and for the near of kin and the orphans and the needy and the wayfarer, so that it may not be a thing taken by turns among the rich of you, and whatever the Messenger gives you, accept it, and from whatever he forbids you, keep back, and be careful of (your duty to) Allah; surely Allah is severe in retributing (evil):
