Musannaf Ibn Abi Shaybah 3577 — Straightening the row

Sayyiduna Jabir bin Samurah (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) said: "Why do you not form rows the way the angels form rows before their Lord?" The people asked: "How do the angels form rows before their Lord?" He (peace and blessings be upon him) said: "They first complete the front rows, and they stand close together in the rows."
