Al-Bara’ b. ‘Azib reported God's Messenger as saying, “When you prostrate yourself, place the palms of your hands on the ground and raise your elbows.” Muslim transmitted it.

وَعَنِ الْبَرَاءِ بْنِ عَازِبٍ قَالَ: قَالَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: إِذَا سَجَدْتَ فضع كفيك وارفع مرفقيك رَوَاهُ مُسلم
