Sahih al-Bukhari 3897
In-book no 3897وَقَالَ لِي خَلِيفَةُ حَدَّثَنَا يَزِيدُ بْنُ زُرَيْعٍ، حَدَّثَنَا سَعِيدٌ، عَنْ قَتَادَةَ، عَنْ أَنَسٍ، عَنْ أَبِي طَلْحَةَ ـ رضى الله عنهما ـ قَالَ كُنْتُ فِيمَنْ تَغَشَّاهُ النُّعَاسُ يَوْمَ أُحُدٍ، حَتَّى سَقَطَ سَيْفِي مِنْ يَدِي مِرَارًا، يَسْقُطُ وَآخُذُهُ، وَيَسْقُطُ فَآخُذُهُ.
Abu Talha (ra) said: I was amongst those who were overtaken by slumber until my sword fell from my hand on several occasions. The sword fell and I picked it up, and it fell again, and I picked it up."
