Abu Qilabah (may Allah have mercy on him) said: Malik bin al-Huwayrith (may Allah be pleased with him) would come to us and say: "Shall I not tell you about the prayer of the Messenger of Allah (peace and blessings be upon him)?" Then he would pray to show us, at a time other than a prayer time. When he raised his head from the second prostration in the first rak'ah, he would sit up straight and then rise, supporting himself on the ground.
