Sahih al-Bukhari
Prophetic Commentary on the Qur'an (Tafseer of the Prophet (pbuh))
The Statement of Allah the Most High: "Then, when they saw it as a dense cloud coming towards their valleys..." (V.46:24)
Narrated `Aisha:
(the wife of the Prophet), I never saw Allah's Messenger (ﷺ) laughing loudly enough to enable me to see his uvula, but he used to smile only. And whenever he saw clouds or winds, signs of deep concern would appear on his face. I said, "O Allah's Messenger (ﷺ)! When people see clouds they usually feel happy, hoping that it would rain, while I see that when you see clouds, one could notice signs of dissatisfaction on your face." He said, "O `Aisha! What is the guarantee for me that there will be no punishment in it, since some people were punished with a wind? Verily, some people saw (received) the punishment, but (while seeing the cloud) they said, 'This cloud will give us rain.' "
