It is narrated from Sayyiduna Abu Malik al-Ash'ari (may Allah be pleased with him) that the Messenger of Allah (peace and blessings be upon him) said: "Listen! By the One in whose Hand is the soul of Muhammad, on the Day of Resurrection a host from among you will be raised up towards Paradise like the dark night, all of them together encompassing the earth. The angels will say: Those who have come with Muhammad are more than those who came with the other prophets."
