The Messenger of Allah ﷺ led us in the dawn prayer at Hudaybiya following a rainfall that had come during the night. When he finished, he turned to the people and asked, "Do you know what your Lord has said?"They replied, "Allah and His Messenger know best."He said, "He said, 'This morning some of My servants have become believers in Me and others disbelievers in Me. Whoever said, we were given rain by the grace of Allah and His mercy, he believes in Me and disbelieves in the stars. But whoever said, we were given rain by such and such a star, he disbelieves in Me and believes in the stars.'"
حدثني يحيى عن مالك عن صالح بن كيسان عن عبيد الله بن عبد الله بن عتبة بن مسعود
صلى لنا رسول الله ﷺ صلاة الصبح بالحديبية على إثر سماء كانت من الليل فلما انصرف أقبل على الناس فقال أتدرون ماذا قال ربكم قالوا الله ورسوله أعلم قال قال أصبح من عبادي مؤمن بي وكافر بي فأما من قال مطرنا بفضل الله ورحمته فذلك مؤمن بي كافر بالكوكب وأما من قال مطرنا بنوء كذا وكذا فذلك كافر بي مؤمن بالكوكب
