[Machine] When this verse was revealed: "And eat and drink until the white thread of dawn becomes distinct to you from the black thread (of night)" (Quran 2:187), I intended to distinguish between two headbands, one black and the other white. So I placed them under my pillow and looked at them, but I couldn't differentiate between the white and the black. When I woke up in the morning, I went to the Messenger of Allah ﷺ and informed him about what I had done. He said, "That is the whiteness of the day and the darkness of the night."
لَمَّا نَزَلَتْ هَذِهِ الْآيَةُ {وَكُلُوا وَاشْرَبُوا حَتَّى يَتَبَيَّنَ لَكُمُ الْخَيْطُ الْأَبْيَضُ} [البقرة 187] مِنَ الْخَيْطِ الْأَسْوَدِ قَالَ عَمَدْتُ إِلَى عِقَالَيْنِ أَحَدُهُمَا أَسْوَدُ وَالْآخَرُ أَبْيَضُ فَجَعَلْتُهُمَا تَحْتَ وِسَادِي قَالَ ثُمَّ جَعَلْتُ أَنْظُرُ إِلَيْهِمَا فَلَا تُبِينُ لِي الْأَسْوَدَ مِنَ الْأَبْيَضِ وَلَا الْأَبْيَضَ مِنَ الْأَسْوَدِ فَلَمَّا أَصْبَحْتُ غَدَوْتُ عَلَى رَسُولِ اللهِ ﷺ فَأَخْبَرْتُهُ بِالَّذِي صَنَعْتُ فَقَالَ إِنْ كَانَ وِسَادُكَ إِذًا لَعَرِيضًا إِنَّمَا ذَلِكَ بَيَاضُ النَّهَارِ مِنْ سَوَادِ اللَّيْلِ
