You said you do not know the existence of Al-illah as a Moon-god. Search google.

You said 'the black stone' muslims are kissing when they go to Mecca is not an idol but you admitted that the hanifan were worshiping it pre-Islamic period. What do you call an object that people worship? God or god? Since people worshiped it, there is no other name for it than idol.

Therefore it was this idol (the black stone) Muhammad retained when he destroyed other idols in Kaaba, Mecca which now forms part of Islamic worship.

If the hanifans actually believed in the true God they would not have created an image (the black stone) for themselves to worship.

Since Abdullah (Muhammad's father) was a hanifan and the hanifans were worshiping 'the black stone' (according to you), it would therefore be right to conclude that Muhammad was used (by Gabriel) to promote the idol of his father.

In that case, you would not expect the message of Islam to tally with that of Christianity as the source is not the same.

This is why Islam differs from Christianity in all vital areas of life like marriage, heaven and how to get there, salvation, sonship, revenge etc as Christianity is from Jesus, the preacher and teacher of God's word and Islam from Muhammad, the promoter of and warner on his father's religion.

It is now left for the muslims to ponder whether or not it is possible to get to heaven through a religion with source from idol worshiping.
