Narrated Qudamah ibn Wabirah: The Prophet ﷺ 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. "

Narrated Al-Ja'd ad-Damri: The Prophet ﷺ said: He who leaves the Friday prayer (continuously) for three Friday on account of slackness, Allah will print a stamp on his heart.
