al-Anwāʾ (Star Rains)

Anwa': attributing rain to the rising and setting of stars — "we have been rained on by such-and-such a star" — which Islam counted as ingratitude for the blessing.

When rain fell they would say "we have been rained on by such-and-such a star", attributing the rain to one of the stars. Then came the Prophet's hadith: whoever says "we were rained on by God's favour and mercy" is a believer in Me and an unbeliever in the star; whoever says "we were rained on by such-and-such a star" is an unbeliever in Me and a believer in the star ¹.
