Whenever the Prophet ﷺ saw a cloud appearing in the sky that looked like it might bring rain, he would pace back and forth, going in and out, and his face would change. But when the rain fell, this would leave him. Ayesha noticed this about him, so the Prophet ﷺ said, "I do not know, perhaps it is as the people said, 'Then when they saw it as a cloud advancing toward their valleys'" [Ahqaf 46:24], and he recited the rest of the verse.
حدثنا مكي بن إبراهيم حدثنا ابن جريج عن عطاء
كان النبي ﷺ إذا رأى مخيلة في السماء أقبل وأدبر ودخل وخرج وتغير وجهه فإذا أمطرت السماء سري عنه فعرفته عائشة ذلك فقال النبي ﷺ ما أدري لعله كما قال قوم {فلما رأوه عارضا مستقبل أوديتهم} الآية
