Sahih al-Bukhari, 2469

Rapporté par Anas : Le Messager d'Allah (ﷺ) fit le serment de ne pas aller voir ses épouses pendant un mois car il s’était foulé le pied. Il resta dans une chambre à l’étage, et ‘Umar alla le voir et lui demanda : « As-tu divorcé de tes femmes ? » Il répondit : « Non, mais j’ai juré de ne pas aller les voir pendant un mois. » Le Prophète y resta vingt-neuf jours, puis il descendit et alla voir ses épouses

Narrated Anas:Allah's Messenger (ﷺ) took an oath that he would not go to his wives for one month as his foot had been sprained. He stayed in an upper room when `Umar went to him and said, "Have you divorced your wives?" He said, "No, but I have taken an oath that I would not go to them for one month." The Prophet stayed there for twenty-nine days, and then came down and went to his wives
