Jabir bin Samura reported,

The Messenger of Allah ﷺ said, "Will you not line up in rows as the angels line up before their Lord?"We asked, "Messenger of Allah, how do the angels line up before their Lord?"He replied, "They complete the front rows first, and they stand closely packed together in each row."
