It is narrated from Abu Abdullah Salim that Uqbah bin Amr (may Allah be pleased with him) said: "Shall I not pray the way I saw the Messenger of Allah (peace and blessings be upon him) praying?" We said: "Of course! Please do show us." So he stood up and began to pray. When he bowed, he placed his palms on his knees, placed his fingers around his knees and kept his armpits apart, until everything settled in its place. Then he raised his head from bowing and stood up straight until every limb settled in its place. Then he prostrated, and again kept his arms apart, until everything settled in its place. Then he sat, likewise with calm, until every limb rested in its place. Then he did the same in all four rak'ahs, and after that he said: "This is how I saw the Messenger of Allah (peace and blessings be upon him) praying, and this is how he used to lead us in prayer."
