23. The Friday service.
A service is held in the principal mosque on Fridays about midday, at which public prayers are held and a sermon or khutbak is preached or recited. Friday is known as Jumah, or the day of assembly. Friday was said by Muhammad to have been the day on which Adam was taken into paradise and turned out of it, the day on which he repented and on which he died. It will also be the day of Resurrection. The Prophet considered that the Jews and Christians had erred in transferring their Sabbath from Friday to Saturday and Sunday respectively.[28]
