Sunan Abi Dawud, Hadith 752 ⓘ
Narrated AbuHurayrah: When the Messenger of Allah began his prayer, he raised his hands extensively.
حَدَّثَنَا مُسَدَّدٌ، حَدَّثَنَا يَحْيَى، عَنِ ابْنِ أَبِي ذِئْبٍ، عَنْ سَعِيدِ بْنِ سَمْعَانَ، عَنْ أَبِي هُرَيْرَةَ، قَالَ كَانَ رَسُولُ اللَّهِ صلى الله عليه وسلم إِذَا دَخَلَ فِي الصَّلاَةِ رَفَعَ يَدَيْهِ مَدًّا .
