I was wonder that exagerrating love will lead you to shirk?I mean Christians love Jesus Christ(pbuh)then slowly by slowly they made him as a god because of too much love,is it true?
Yes, it is true. In islam, muslims are stricly ordered not to praise the Prophets so much that they give them status near to or like or even Above God.
Here is one hadith about it:
Umar ibn Al-Khattab reported: The Messenger of Allah, peace and blessings be upon him, said, “Do not exaggerate my praises as the Christians have done with the son of Mary. Verily, I am only a servant, so refer to me as the servant of Allah and his messenger.”
