It is narrated from Sayyiduna Abdullah bin Zaid (may Allah be pleased with him), he says: When we reached the morning, we presented ourselves before the Messenger of Allah (peace and blessings be upon him). I related to him the dream (regarding the adhan), so the Prophet (peace and blessings be upon him) said: "Indeed, this is a true dream. Stand with Bilal, for he has a louder voice than you. Teach him the words that were shown to you (in the dream), and he should call the adhan with them." He says: So I complied with the order of the Prophet (peace and blessings be upon him). Then, when Sayyiduna Umar bin Khattab (may Allah be pleased with him) heard Bilal (may Allah be pleased with him) giving the adhan for prayer, he came out dragging his cloak towards the Messenger of Allah (peace and blessings be upon him) and said: O Messenger of Allah, by the One who has sent you with the truth, indeed I have seen the same as he has called out. So the Messenger of Allah (peace and blessings be upon him) said: "Then all praise is for Allah alone (Who has made this dream come true)."
