[Machine] The Messenger of Allah ﷺ said, "Whoever catches a rakah from Jumu'ah prayer, let him pray another rakah with it. If he catches them sitting, let him pray four. It is narrated from another perspective other than that of Al-Zuhri, which we have mentioned in the difference of opinion. It is also narrated from Abu Salih from Abu Hurairah, in a statement attributed to him."
