Sayyiduna Salman bin Khalid (may Allah be pleased with him), who was probably from the tribe of Khuza'ah, narrates that he prayed and felt at ease, and it was as if the people found fault with him for that. At this he said: I heard the Messenger of Allah (peace and blessings be upon him) say: "O Bilal! Establish the prayer and give us rest."
