Sayyiduna Abdullah bin Abbas (may Allah be pleased with them both) narrates: One of the Ansari companions of the Prophet (peace and blessings be upon him) told me that once they were sitting with the Prophet (peace and blessings be upon him) when suddenly a star fell and a flash of light appeared. The Prophet (peace and blessings be upon him) asked them, "When such a star used to fall, what did you people think in the days of ignorance?" The people replied, "We used to say that tonight a great man will be born or a great man will die." The Prophet (peace and blessings be upon him) said: "They do not fall because of anyone's death or birth, but when our Lord decrees a matter, the angels who carry the Throne glorify Him, then the angels who are next to them glorify Him, until this glorification reaches the lowest heaven. The angels who are near the Throne (i.e., the angels of the seventh heaven) ask, 'What has our Lord said?' So (the angels carrying the Throne) inform them about it. In the same way, all the angels of the heavens inform those of the heaven below them, until this matter reaches the lowest heaven. Then a jinn snatches it and conveys it to his friends, and he mixes it with something else. So when (something a soothsayer says) turns out to be true, it is because of that truth, but they add many lies to it (that is why many of their statements also turn out to be false)."
Here, the narrator named Mubashir is in doubt; perhaps these are the words: "They add to this matter."

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.

Sayyiduna Qabeesah bin Mukhaariq (may Allah be pleased with him) narrates: I heard the Prophet (peace and blessings of Allah be upon him) say:“Divination by birds, omens, and drawing lines are from Satan.”

(Imam Ibn Hibban, may Allah have mercy on him, says:) By“drawing lines”is meant belief in astrology, and by“drawing lines”is also meant playing with stones for idols.

Sayyiduna Zaid bin Khalid al-Juhani رضي الله عنه narrates: At Hudaybiyyah, the Prophet صلى الله عليه وسلم led us in the morning prayer after it had rained during the night. When the Prophet صلى الله عليه وسلم finished the prayer, he turned towards the people and said, "Do you know what your Lord has said?" The people replied, "Allah and His Messenger know best." The Prophet صلى الله عليه وسلم said, "Allah has said: Some of My servants have believed in Me and some have disbelieved in Me. Whoever says, 'We have received rain by the grace and mercy of Allah,' he is a believer in Me and a disbeliever in the stars. And whoever says, 'We have received rain due to such-and-such star,' he is a disbeliever in Me and a believer in the stars."

Sayyiduna Abu Hurairah (may Allah be pleased with him) narrates that the Prophet (peace and blessings of Allah be upon him) said: "There is no reality in contagion, the owl, Safar, and the star."

Sayyiduna Abdullah bin Umar (may Allah be pleased with them both) narrates this statement of the Noble Prophet (peace and blessings of Allah be upon him): "The keys of knowledge are five, which none knows except Allah Almighty: No person knows what will come forth from the womb, only Allah knows; and no person knows what will happen tomorrow, only Allah knows; no one knows when it will rain, only Allah knows. No person knows where he will die, only Allah knows. No person knows when the Hour (Day of Judgment) will come, only Allah knows."

Sayyiduna Anas (may Allah be pleased with him) narrates: Rain fell upon us while we were with the Prophet (peace and blessings of Allah be upon him), so the Prophet (peace and blessings of Allah be upon him) removed his garment for the rain. We said: O Messenger of Allah (peace and blessings of Allah be upon him)! Why did you do this? He (peace and blessings of Allah be upon him) said: Because it has just come from the presence of the Lord.
