Arabic

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.‏

Translation

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
