Abu Talha (ra) said:
وَقَالَ 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 .
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."
