أَخْبَرَنَا أَبُو الْوَلِيدِ ، حَدَّثَنَا شَرِيكٌ ، عَنْ حُصَيْنٍ ، عَنْ الشَّعْبِيِّ ، عَنْ عَدِيِّ بْنِ حَاتِمٍ ، قَالَ : قُلْتُ : يَا رَسُولَ اللَّهِ، لَقَدْ جَعَلْتُ تَحْتَ وِسَادَتِي خَيْطًا أَبْيَضَ وَخَيْطًا أَسْوَدَ، فَمَا تَبَيَّنَ لِي شَيْءٌ.
قَالَ : " إِنَّكَ لَعَرِيضُ الْوِسَادِ، وَإِنَّمَاذَلِكَ اللَّيْلُ مِنْ النَّهَارِ فِي قَوْلِهِ تَعَالَى : # وَكُلُوا وَاشْرَبُوا حَتَّى يَتَبَيَّنَ لَكُمُ الْخَيْطُ الأَبْيَضُ مِنَ الْخَيْطِ الأَسْوَدِ مِنَ الْفَجْرِ ثُمَّ أَتِمُّوا الصِّيَامَ إِلَى اللَّيْلِ وَلا تُبَاشِرُوهُنَّ وَأَنْتُمْ عَاكِفُونَ فِي الْمَسَاجِدِ تِلْكَ حُدُودُ اللَّهِ فَلا تَقْرَبُوهَا كَذَلِكَ يُبَيِّنُ اللَّهُ آيَاتِهِ لِلنَّاسِ لَعَلَّهُمْ يَتَّقُونَ سورة البقرة آية 187 # "

He said: “Indeed, you are as wide as a pillow, but that is night from day in the Almighty’s saying: #And eat and drink until the white thread of The black thread of dawn, then complete the fast until the night, and do not associate with them while you are secluded in the mosques.
