378. Narrated Anas bin Mālik رضي الله عنه: Once Allāh's Messenger ﷺ fell off a horse and his leg or shoulder got injured. He swore that he would not go to his wives for one month and he stayed in a Mashruba (attic room) having stairs made of date palm trunks. So his Companions came to visit him, and he led them in Ṣalāt (prayer) sitting, whereas his Companions were standing. When he finished the Ṣalāt, he said, "Imām is meant to be followed, so when he says Allāhu Akbar, say Allāhu Akbar and when he bows, bow and when he prostrates, prostrate and if he offers Ṣalāt standing offer Ṣalāt standing(1). After the 29th day the Prophet ﷺ came down (from the attic room) and the people asked him, "O Allāh's Messenger! You swore that you will not go to your wives for one month." He said, "The month is of 29 days."
