ABSTRACT
It is true that Islam did not have a history of worship like that of Christianity, but Islamic worship has its own history. The Prophet's innovation had to undergo the fundamental influence of the existing environment in the field of worship as well. The Friday service is one of only three occasions of community worship in the Islamic ecclesiastical year, the other two being, respectively, the feasts of fast-breaking and sacrifice. There are several other small features that refer to the pre-Mass. Taken individually these do not carry much weight, but together with everything else they heighten the probability of connections between Christian and Muslim liturgies. Muhammad takes over this role with his position in his congregation. The Christian influence on Muslim worship is all the less wondrous aus the dependence of Islam on Christianity is apparent even in dogma, to say nothing of the secular sphere.
