Sahih Muslim
حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ أَخْبَرَنَا عُبَيْدُ اللَّهِ بْنُ إِيَادٍ، عَنْ إِيَادٍ، عَنِ الْبَرَاءِ، قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " إِذَا سَجَدْتَ فَضَعْ كَفَّيْكَ وَارْفَعْ مِرْفَقَيْكَ " .
Al-Bira' (b. 'Azib) reported: The Messenger of Allah (ﷺ) said. When you prostrate yourself, place the palms of your hands on the ground and raise your elbows.
