The list of reasons that Muhammad's followers prostrate themselves toward the Quraish pagan's black stone idol in Mecca five times a day, is the very same list of reasons, that Muslims kiss that black stone idol.
Narrated 'Abis bin Rabia: 'Umar came near the Black stone and kissed it and said "No doubt, I know that you are a stone and can neither benefit anyone nor harm anyone. Had I not seen Allah's Apostle kissing you I would not have kissed you." (Book #26, Hadith #667)
That list of reasons Muhammad's followers prostrate themselves toward the Quraish pagan's black stone idol five times a day, is
the same as the list of reasons that they follow Muhammad alone -
because of their faith in Muhammad alone.
