(4) باب الشَّهْرُ يَكُونُ تِسْعًا وَعِشْرِينَ
Abu Zubair is reported to have heard Jabir b. 'Abdullah (Allah be pleased with both of them) as saying:
The Apostle of Allah (ﷺ) separated himself from his wives for a month. (His wives said: ) He came to us on the morning of the twenty-ninth. Upon this some, of the people said: It is the morning of twenty- ninth (according to our calculation). Upon this the Messenger of Allah (ﷺ) said: The month. may also consist of twenty-nine days. The Apostle of Allah (ﷺ) then flapped his bands thrice, twice with all the fingers of both his hand (to indicate twenty-nine) and by the third time with nine (fingers). (ES)
