Sayyiduna Abu Sa‘id Khudri (may Allah be pleased with him) narrates that the Prophet Muhammad (peace and blessings be upon him) said: “If Allah Almighty were to withhold rain from the people for seven years and then send it down, a group among those people would still deny (the truth) and say: ‘Rain has come to us because of the star Mujdah.’”
(Imam Ibn Hibban, may Allah have mercy on him, says:) Mujdah refers to ‘Dabaran’, and it is the fourth station among the lunar mansions.
