1. 2:259 أَوْ كَٱلَّذِى مَرَّ عَلَىٰ قَرْيَةٍ وَهِىَ خَاوِيَةٌ عَلَىٰ عُرُوشِهَا قَالَ أَنَّىٰ يُحْىِۦ هَٰذِهِ ٱللَّهُ بَعْدَ مَوْتِهَا فَأَمَاتَهُ ٱللَّهُ مِا۟ئَةَ عَامٍ ثُمَّ بَعَثَهُۥ قَالَ كَمْ لَبِثْتَ قَالَ لَبِثْتُ يَوْمًا أَوْ بَعْضَ يَوْمٍ قَالَ بَل لَّبِثْتَ مِا۟ئَةَ عَامٍ فَٱنظُرْ إِلَىٰ طَعَامِكَ وَشَرَابِكَ لَمْ يَتَسَنَّهْ وَٱنظُرْ إِلَىٰ حِمَارِكَ وَلِنَجْعَلَكَ ءَايَةً لِّلنَّاسِ وَٱنظُرْ إِلَى ٱلْعِظَامِ كَيْفَ نُنشِزُهَا ثُمَّ نَكْسُوهَا لَحْمًا فَلَمَّا تَبَيَّنَ لَهُۥ قَالَ أَعْلَمُ أَنَّ ٱللَّهَ عَلَىٰ كُلِّ شَىْءٍ قَدِيرٌ

   Or the like of him (Uzair) who passed by a town, and it had fallen down upon its roofs; he said: When will Allah give it life after its death? So Allah caused him to die for a hundred years, then raised him to life. He said: How long have you tarried? He said: I have tarried a day, or a part of a day. Said He: Nay! you have tarried a hundred years; then look at your food and drink-- years have not passed over it; and look at your ass; and that We may make you a sign to men, and look at the bones, how We set them together, then clothed them with flesh; so when it became clear to him, he said: I know that Allah has power over all things.
   

2. 4:34 ٱلرِّجَالُ قَوَّٰمُونَ عَلَى ٱلنِّسَآءِ بِمَا فَضَّلَ ٱللَّهُ بَعْضَهُمْ عَلَىٰ بَعْضٍ وَبِمَآ أَنفَقُوا۟ مِنْ أَمْوَٰلِهِمْ فَٱلصَّٰلِحَٰتُ قَٰنِتَٰتٌ حَٰفِظَٰتٌ لِّلْغَيْبِ بِمَا حَفِظَ ٱللَّهُ وَٱلَّٰتِى تَخَافُونَ نُشُوزَهُنَّ فَعِظُوهُنَّ وَٱهْجُرُوهُنَّ فِى ٱلْمَضَاجِعِ وَٱضْرِبُوهُنَّ فَإِنْ أَطَعْنَكُمْ فَلَا تَبْغُوا۟ عَلَيْهِنَّ سَبِيلًا إِنَّ ٱللَّهَ كَانَ عَلِيًّا كَبِيرًا

   Men are the maintainers of women because Allah has made some of them to excel others and because they spend out of their property; the good women are therefore obedient, guarding the unseen as Allah has guarded; and (as to) those on whose part you fear desertion, admonish them, and leave them alone in the sleeping-places and beat them; then if they obey you, do not seek a way against them; surely Allah is High, Great.
   

3. 4:128 وَإِنِ ٱمْرَأَةٌ خَافَتْ مِنۢ بَعْلِهَا نُشُوزًا أَوْ إِعْرَاضًا فَلَا جُنَاحَ عَلَيْهِمَآ أَن يُصْلِحَا بَيْنَهُمَا صُلْحًا وَٱلصُّلْحُ خَيْرٌ وَأُحْضِرَتِ ٱلْأَنفُسُ ٱلشُّحَّ وَإِن تُحْسِنُوا۟ وَتَتَّقُوا۟ فَإِنَّ ٱللَّهَ كَانَ بِمَا تَعْمَلُونَ خَبِيرًا

   And if a woman fears ill usage or desertion on the part of her husband, there is no blame on them, if they effect a reconciliation between them, and reconciliation is better, and avarice has been made to be present in the (people's) minds; and if you do good (to others) and guard (against evil), then surely Allah is aware of what you do.
   

4. 58:11 يَٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوٓا۟ إِذَا قِيلَ لَكُمْ تَفَسَّحُوا۟ فِى ٱلْمَجَٰلِسِ فَٱفْسَحُوا۟ يَفْسَحِ ٱللَّهُ لَكُمْ وَإِذَا قِيلَ ٱنشُزُوا۟ فَٱنشُزُوا۟ يَرْفَعِ ٱللَّهُ ٱلَّذِينَ ءَامَنُوا۟ مِنكُمْ وَٱلَّذِينَ أُوتُوا۟ ٱلْعِلْمَ دَرَجَٰتٍ وَٱللَّهُ بِمَا تَعْمَلُونَ خَبِيرٌ

   O you who believe! when it is said to you, Make room in (your) assemblies, then make ample room, Allah will give you ample, and when it is said: Rise up, then rise up. Allah will exalt those of you who believe, and those who are given knowledge, in high degrees; and Allah is Aware of what you do.
