Sayyiduna Jabir bin Samurah (may Allah be pleased with him) narrates: The Prophet (peace and blessings be upon him) came to the mosque. He said: Why do you not form rows as the angels form rows before their Lord? The people asked: O Messenger of Allah (peace and blessings be upon him)! How do the angels form rows before their Lord? The Prophet (peace and blessings be upon him) said: They complete the first row first and then do not leave any gaps in the rows.
