Sahih al-Bukhari, Hadith 4068 ⓘ
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."
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.
