Sahih Muslim Book 1, Hadith Number 134.

Chapter : The unbelief of one who said: We got rainfall by the movement (of the stars).

It is reported on the authority of Abu Huraira that the Messenger of Allah (may peace and blessing be upon him) observed: Allah does not shower His blessings from the heaven that in the morning a group of men disbelieve it (to be a blessing from Allah). Allah sends down rain, but they (the disbelievers) say: Such and such star (is responsible for that).
