1. 2:187 أُحِلَّ لَكُمْ لَيْلَةَ ٱلصِّيَامِ ٱلرَّفَثُ إِلَىٰ نِسَآئِكُمْ هُنَّ لِبَاسٌ لَّكُمْ وَأَنتُمْ لِبَاسٌ لَّهُنَّ عَلِمَ ٱللَّهُ أَنَّكُمْ كُنتُمْ تَخْتَانُونَ أَنفُسَكُمْ فَتَابَ عَلَيْكُمْ وَعَفَا عَنكُمْ فَٱلْـَٰٔنَ بَٰشِرُوهُنَّ وَٱبْتَغُوا۟ مَا كَتَبَ ٱللَّهُ لَكُمْ وَكُلُوا۟ وَٱشْرَبُوا۟ حَتَّىٰ يَتَبَيَّنَ لَكُمُ ٱلْخَيْطُ ٱلْأَبْيَضُ مِنَ ٱلْخَيْطِ ٱلْأَسْوَدِ مِنَ ٱلْفَجْرِ ثُمَّ أَتِمُّوا۟ ٱلصِّيَامَ إِلَى ٱلَّيْلِ وَلَا تُبَٰشِرُوهُنَّ وَأَنتُمْ عَٰكِفُونَ فِى ٱلْمَسَٰجِدِ تِلْكَ حُدُودُ ٱللَّهِ فَلَا تَقْرَبُوهَا كَذَٰلِكَ يُبَيِّنُ ٱللَّهُ ءَايَٰتِهِۦ لِلنَّاسِ لَعَلَّهُمْ يَتَّقُونَ

   It is made lawful to you to go into your wives on the night of the fast; they are an apparel for you and you are an apparel for them; Allah knew that you acted unfaithfully to yourselves, so He has turned to you (mercifully) and removed from you (this burden); so now be in contact with them and seek what Allah has ordained for you, and eat and drink until the whiteness of the day becomes distinct from the blackness of the night at dawn, then complete the fast till night, and have not contact with them while you keep to the mosques; these are the limits of Allah, so do not go near them. Thus does Allah make clear His communications for men that they may guard (against evil).
   

2. 3:39 فَنَادَتْهُ ٱلْمَلَٰٓئِكَةُ وَهُوَ قَآئِمٌ يُصَلِّى فِى ٱلْمِحْرَابِ أَنَّ ٱللَّهَ يُبَشِّرُكَ بِيَحْيَىٰ مُصَدِّقًۢا بِكَلِمَةٍ مِّنَ ٱللَّهِ وَسَيِّدًا وَحَصُورًا وَنَبِيًّا مِّنَ ٱلصَّٰلِحِينَ

   On the day when (some) faces shall turn white and (some) faces shall turn black; then as to those whose faces turn black: Did you disbelieve after your believing? Taste therefore the chastisement because you disbelieved.
   

4. 12:25 وَٱسْتَبَقَا ٱلْبَابَ وَقَدَّتْ قَمِيصَهُۥ مِن دُبُرٍ وَأَلْفَيَا سَيِّدَهَا لَدَا ٱلْبَابِ قَالَتْ مَا جَزَآءُ مَنْ أَرَادَ بِأَهْلِكَ سُوٓءًا إِلَّآ أَن يُسْجَنَ أَوْ عَذَابٌ أَلِيمٌ

   And they shall say: O our Lord! surely we obeyed our leaders and our great men, so they led us astray from the path;

   Do you not see that Allah sends down water from the cloud, then We bring forth therewith fruits of various colors; and in the mountains are streaks, white and red, of various hues and (others) intensely black?

   And when one of them is given news of that of which he sets up as a likeness for the Beneficent Allah, his face becomes black and he is full of rage.
