﴿ أُحِلَّ لَكُمْ لَيْلَةَ ٱلصِّيَامِ ٱلرَّفَثُ إِلَىٰ نِسَآئِكُمْ ۚ هُنَّ لِبَاسٌۭ لَّكُمْ وَأَنتُمْ لِبَاسٌۭ 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 lawful for you to go in unto your wives during the night preceding the [day's] fast: they are as a garment for you, and you are as a garment for them. God is aware that you would have deprived yourselves of this right, and so He has turned unto you in His mercy and removed this hardship from you. Now, then, you may lie with them skin to skin, and avail yourselves of that which God has ordained for you, and eat and drink until you can discern the white streak of dawn against the blackness of night, and then resume fasting until nightfall; but do not lie with them skin to skin when you are about to abide in meditation in houses of worship. These are the bounds set by God: do not, then, offend against them - [for] it is thus that God makes clear His messages unto mankind, so that they might remain conscious of Him.”

(It is made lawful for you to go in unto your wives on the night of the fast...) [2:187]. According to the report of al-Walibi, Ibn �Abbas said: �This is because after the nightfall (�Isha�) prayer during Ramadan, the Muslims were forbidden to have food or sex until the following night. But some Muslims, among whom were �Umar ibn al-Khattab, complained to Allah�s Messenger, Allah bless him and give him peace, about this. And so Allah, exalted is He, revealed this verse�. Abu Bakr al-Asfahani informed us> Abu�l-Shaykh al-Hafiz> �Abd al-Rahman ibn Muhammad al-Razi> Sahl ibn �Uthman al-�Askari> Yahya ibn Abi Za�idah> his father and others> Abu Ishaq> al-Bara� ibn �Azib who said: �After breaking their fast, the Muslims used to be allowed to eat, drink and have sexual intercourse for as long as they did not sleep. Once they went to sleep, they were forbidden to do all these things until the following day when they broke their fast. Qays ibn Sirma al-Ansari went to his wife at the time of breaking the fast. His wife went out to get something [to eat]. While he was waiting, he fell asleep [and therefore could not eat until the following night]. The following day he fainted in the middle of the day. �Umar ibn al-Khattab also had sexual intercourse with his wife after he found her sleeping. He mentioned what had happened to the Prophet, Allah bless him and give him peace, and the verse was (is made lawful for you to go in unto your wives on the night of the fast�) was revealed, up to Allah�s saying (�of the dawn.). The Muslims were very happy with this�. Abu �Abd al-Rahman ibn Abi Hamid> Muhammad ibn �Abd Allah ibn Muhammad al-Shaybani> Muhammad ibn �Abd al-Rahman al-Daghuli> al-Za�farani> Shababah> Isra�il> Abu Ishaq> al-Bara� who said: �The Companions of Muhammad, Allah bless him and give him peace, when one of them was fasting and was still sleeping at the advent of the time of breaking the fast, he was not allowed to eat that night or the following day until the advent of the time of breaking the fast of the following day. Qays ibn Sirma al-Ansari was fasting. When the time of breaking fast came, he went to his wife and asked her: �Do you have any food?� She said: �No! But I will go and find something for you�.
