Jabir b. Samura told that he heard Allah's Messenger ﷺ say, “There are three things I fear for my people

seeking rain by the stars,*the injustice of the ruler, and denial of Allah's decree.” Ahmad. *This is a reference to the pre-Islamic habit of attributing rain to certain seasons and saying the rain came to them because of a certain star, whereas Muslims ought to recognize that rain comes by Allah’s favour.
