Narrated Qudamah ibn Wabirah: The Prophet صلی اللہ علیہ وسلم said: If anyone omits the Friday prayer without excuse, he must give one dirham or half a dirham, or one sa' or half a sa' of wheat, in alms. Abu Dawud said: Saeed bin Bashir reported this tradition in a like manner, except that he narrated one mudd or half mudd (instead of sa'). He narrated it from Samurah. Abu Dawud said: I heard Ahmad bin Hanbal being asked about the differences over the narration of this Hadith. He said: Hammam has a stronger memory - in my opinion - than Ayyub.
