English translation
669. Narrated Abū Sa'īd Al-Khudrī رضي الله عنه: A cloud came and it rained till the roof (of the mosque) started leaking, and in those days the roof used to be of the branches of date-palms. Iqāma was pronounced and I saw Allāh's Messenger ﷺ prostrating in water and mud and even I saw the mark of mud on his forehead.
