He used to relate that while they were with the Messenger of Allah ﷺ they wiped themselves with earth for the Fajr prayer. They struck the ground with their palms and wiped their faces with a single wipe, then struck the ground with their palms a second time and wiped their arms entirely, up to the shoulders and the armpits, along the inner sides of their arms.He said that the Muslims stood and struck the dust with their palms without taking up any of the dust, and he mentioned something similar, but he did not mention the shoulders and the armpits.Ibn Layth said, "Up to above the elbows."
حدثنا سليمان بن داود المهري وعبد الملك بن شعيب عن ابن وهب نحو هذا الحديث قال قام المسلمون فضربوا بأكفهم التراب ولم يقبضوا من التراب شيئا فذكر نحوه ولم يذكر المناكب والآباط قال ابن الليث إلى ما فوق المرفقين
