Ruling on the call to rapprochement between religions

Question: Is the call for rapprochement between religions (Islaam – Christianity – Judaism) a legitimate one? Is it permissible for a Muslim believer to support it? I heard that this is done by some scholars in Al-Azhar and other Islaamic institutions. Is the call for rapprochement between Ahl-ul-Sunnah wal-Jamaa`ah (adherents to the Sunnah and the Muslim mainstream) and the Shiites, Druze, Al-Ismaa`iliyyah, Al-Nusayriyyah and such sects useful for Muslims?

Is reconciliation between them possible, although all of these sects entail Shirk (associating others with Allaah in His Divinity or worship), offense to the Messenger of Allah (peace be upon him), and hostility towards Islam and Ahl-ul-Sunnah wal-Jamaa`ah?

Question: A dispute arose among us over the judgment on a Muslim who wears a cross pendant, which is a symbol of Christianity. Some maintain that such a person is a disbeliever with no need to discuss his reasons for wearing it. Others maintain that such a person should not be judged a disbeliever until he has been discussed and it has been made clear to him that wearing a cross is Haraam for a Muslim and that it is a symbol of Christianity. If he still insists on wearing it, he will be regarded as a disbeliever.

Answer: This matter and the like must be detailed and made clear. This person should be informed of the ruling on wearing the cross and that it is a symbol of Christianity. Moreover, he should be informed that wearing a cross is an indication of being satisfied with and belonging to the Christians and their beliefs… read more here.
