Allah's Statement: "...He sent down security for you. Slumber..." (V.3:154)
حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ بْنِ عَبْدِ الرَّحْمَنِ أَبُو يَعْقُوبَ، حَدَّثَنَا حُسَيْنُ بْنُ مُحَمَّدٍ، حَدَّثَنَا شَيْبَانُ، عَنْ قَتَادَةَ، حَدَّثَنَا أَنَسٌ، أَنَّ أَبَا طَلْحَةَ، قَالَ غَشِيَنَا النُّعَاسُ وَنَحْنُ فِي مَصَافِّنَا يَوْمَ أُحُدٍ ـ قَالَ ـ فَجَعَلَ سَيْفِي يَسْقُطُ مِنْ يَدِي وَآخُذُهُ، وَيَسْقُطُ وَآخُذُهُ.
Narrated Abu Talha: Slumber overtook us during the battle of Uhud while we were in the front files. My sword would fall from my hand and I would pick it up, and again it would fall down and I would pick it up again.
