surah 17:90-94 of the qur'an tells about how, when muhammad was challenged to perform a miracle and prove he was from the true god, he could not perform any and here he actually says himself: "am i anything but a man,- a messenger?".
- surah 29:27 states clearly that, as far as allah and the qur'an are concerned, the only true prophets are those related to isaac (ishaq) or jacob (yaqoub); yet muhammad, according to muslim tradition, is related to ishmael and not isaac or jacob.
accordingly, why should i follow muham-mad who confess to all that he is just a man per surah 17: 90-94?
why should i follow muham-mad, who is not even in a prophetic bloodline according to koran surah 29: 27?
