Surah Al-Baqarah, ayah 187

أُحِلَّ لَكُمۡ لَيۡلَةَ ٱلصِّيَامِ ٱلرَّفَثُ إِلَىٰ نِسَآئِكُمۡۚ هُنَّ لِبَاسٞ لَّكُمۡ وَأَنتُمۡ لِبَاسٞ لَّهُنَّۗ عَلِمَ ٱللَّهُ أَنَّكُمۡ كُنتُمۡ تَخۡتَانُونَ أَنفُسَكُمۡ فَتَابَ عَلَيۡكُمۡ وَعَفَا عَنكُمۡۖ فَٱلۡـَٰٔنَ بَٰشِرُوهُنَّ وَٱبۡتَغُواْ مَا كَتَبَ ٱللَّهُ لَكُمۡۚ وَكُلُواْ وَٱشۡرَبُواْ حَتَّىٰ يَتَبَيَّنَ لَكُمُ ٱلۡخَيۡطُ ٱلۡأَبۡيَضُ مِنَ ٱلۡخَيۡطِ ٱلۡأَسۡوَدِ مِنَ ٱلۡفَجۡرِۖ ثُمَّ أَتِمُّواْ ٱلصِّيَامَ إِلَى ٱلَّيۡلِۚ وَلَا تُبَٰشِرُوهُنَّ وَأَنتُمۡ عَٰكِفُونَ فِي ٱلۡمَسَٰجِدِۗ تِلۡكَ حُدُودُ ٱللَّهِ فَلَا تَقۡرَبُوهَاۗ كَذَٰلِكَ يُبَيِّنُ ٱللَّهُ ءَايَٰتِهِۦ لِلنَّاسِ لَعَلَّهُمۡ يَتَّقُونَ ١٨٧

It has been made permissible for you the night preceding fasting to go to your wives [for sexual relations]. They are a clothing for you and you are a clothing⁶⁷ for them. Allāh knows that you used to deceive yourselves,⁶⁸ so He accepted your repentance and forgave you. So now, have relations with them and seek that which Allāh has decreed for you [i.e., offspring]. And eat and drink until the white thread of dawn becomes distinct to you from the black thread [of night]. Then complete the fast until the night [i.e., sunset]. And do not have relations with them as long as you are staying for worship in the mosques. These are the limits [set by] Allāh, so do not approach them. Thus does Allāh make clear His verses [i.e., ordinances] to the people that they may become righteous.
