It was the custom among the companions of Muhammad that if any of them was fasting and the food was presented (for breaking his fast), but he slept before eating, he would not eat that night and the following day till sunset. Qais bin Sirma-al-Ansari was fasting and came to his wife at the time of Iftar (breaking one's fast) and asked her whether she had anything to eat. She replied, "No, but I would go and bring some for you." He used to do hard work during the day, so he was overwhelmed by sleep and slept. When his wife came and saw him, she said, "Disappointment for you." When it was midday on the following day, he fainted and the Prophet ﷺ was informed about the whole matter and the following verses were revealed: "You are permitted To go to your wives (for sexual relation) At the night of fasting." So, they were overjoyed by it. And then Allah also revealed: "And eat and drink Until the white thread Of dawn appears to you Distinct from the black thread (of the night)." (2.187)  

كَانَ أَصْحَابُ مُحَمَّدٍ ﷺ إِذَا كَانَ الرَّجُلُ صَائِمًا فَحَضَرَ الإِفْطَارُ فَنَامَ قَبْلَ أَنْ يُفْطِرَ لَمْ يَأْكُلْ لَيْلَتَهُ وَلاَ يَوْمَهُ حَتَّى يُمْسِيَ وَإِنَّ قَيْسَ بْنَ صِرْمَةَ الأَنْصَارِيَّ كَانَ صَائِمًا فَلَمَّا حَضَرَ الإِفْطَارُ أَتَى امْرَأَتَهُ فَقَالَ لَهَا أَعِنْدَكِ طَعَامٌ قَالَتْ لاَ وَلَكِنْ أَنْطَلِقُ فَأَطْلُبُ لَكَ وَكَانَ يَوْمَهُ يَعْمَلُ فَغَلَبَتْهُ عَيْنَاهُ فَجَاءَتْهُ امْرَأَتُهُ فَلَمَّا رَأَتْهُ قَالَتْ خَيْبَةً لَكَ فَلَمَّا انْتَصَفَ النَّهَارُ غُشِيَ عَلَيْهِ فَذُكِرَ ذَلِكَ لِلنَّبِيِّ ﷺ فَنَزَلَتْ هَذِهِ الآيَةُ {أُحِلَّ لَكُمْ لَيْلَةَ الصِّيَامِ الرَّفَثُ إِلَى نِسَائِكُمْ} فَفَرِحُوا بِهَا فَرَحًا شَدِيدًا وَنَزَلَتْ {وَكُلُوا وَاشْرَبُوا حَتَّى يَتَبَيَّنَ لَكُمُ الْخَيْطُ الأَبْيَضُ مِنَ الْخَيْطِ الأَسْوَدِ}

Qais bin Sirmah Al-Ansari fasted and came to his wife at the time of Iftar, and said to her: 'No, but I will go and bring something for you.' He worked during the day, so his eyes (sleep) overcame him. Then his wife came, and when she saw him she said: 'You shall be disappointed.' About the middle of the next day he fainted. That was mentioned to the Prophet ﷺ, so this Ayah was revealed: 'It is made lawful for you to have sexual relations with your women on the night of the fasts. So they were very happy about that. 'And eat and drink until the white thread (light) of dawn appears distinct to you from the black thread (of night). (2:187)'" (Using translation from Tirmidhī 2968)

[Machine] No, but I set off to find. And it was his day to work in his land, so his eyes were tired. Then his wife came, and when she saw him, she said, "What a disappointment for you." So he woke up and the day did not end until he was unconscious. She mentioned that to the Prophet, ﷺ , so this verse was revealed: "Permitted to you, on the night of the Fast, is approach to your wives. They are your garments and ye are their garments." [Al-Baqarah 187]. They were extremely happy with it. "Then complete your Fast till the night appears." [Al-Baqarah 187]. This is the wording of the hadith of Al-Husayn ibn Hambash.
