question #3 Sahih al-Bukhari 5289, Book 68, Hadith 38 : What can be learned from the Prophet’s (ﷺ) actions regarding fulfilling oaths and commitments?

Allah’s Messenger (ﷺ) took an oath that he would abstain from his wives, and at that time his leg had been
sprained (dislocated). So he stayed in the Mashruba (an attic room) of his for 29 days. Then he came
down, and they (the people) said, “O Allah’s Messenger (ﷺ)! You took an oath to abstain from your wives for
one month.” He said, “The month is of twenty nine days.”
