Zaid b. Khalid al-Juhani said: God’s messenger led us in the morning prayer at al-Hudaibiya after rain which had fallen during the night, and when he finished he turned to the people and said, “Do you know what your Lord has said?” On their replying that God and His messsenger knew best he told them that He had said, “This morning there were among my servants one who believes in me and one who disbelieves. The one who said, ‘We have been given rain by God’s grace and mercy' is the one who believes in me and disbelieves in the star, but the one who said, ‘We have been given rain by such and such a rainy star’ is the one who disbelieves in me and believes in the star.” (Bukhari and Muslim.)
