Silsilat al-Ahadith al-Sahihah

Sayyiduna Abu Darda (may Allah be pleased with him) narrates: In the time of the Messenger of Allah (peace and blessings be upon him), there was a drought. We requested him to pray for rain. He (peace and blessings be upon him) prayed for rain (and rain did descend). When morning came, he (peace and blessings be upon him) heard some people saying: "Rain has come because of such-and-such star." The Noble Prophet (peace and blessings be upon him) said: "Whenever Allah bestows a favor upon His servants, they become disbelievers because of it."
