It is narrated from Alqamah (may Allah have mercy on him) that Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) said: I will certainly lead you in prayer the way the Messenger of Allah (peace and blessings be upon him) prayed. Then he led the prayer, and in it he raised his hands only once (at the beginning).
