I apologise for intruding on any running conversation. This is to bring a discussion over from another thread:
Proud Muslim: "you may not degrade Islam by offering other religion"
Like many Muslims, many Christians believe that living their lives as an example to others is the highest form of witness to others of the truth of their faith. Many devout Christians I have known of many sects ( andy sect that has long been in the Mideast in fact) considers it highly inappropriate to attempt "conversion" of someone from onother belief, especially by attacking another belief. I grew up around Christians and Muslims who got along very well.
Your remarks seem to me to hark back to the Crusades, and not the Qur'an. It was not long after Crusade, when a leading Muslim very clearly and admirably tried to set things right for the future.
When Calif Umar ibn al-Khattab returned to Jerusalem in 633, as you probably know, Christian officials asked that he spread his carpet in the Church of the Holy Sepulchre to pray. He refused, on the grounds that future Muslims would be likely to convert the place into a mosque, only because he had once prayed there. Instead, the Caliph's carpet was carried to the top of the steps outside the church, to where as you know the Mosque of Umar now stands- Many consider this the second holiest place of Islam. I think that in his tolerance, the Caliph acted in accordance with the Qur'an, and as a result the Church of the Holy Sepuchre is to this day celebrating and promoting Christianity among Muslims.
Islam, as the divine law of a supreme being, already applies everywhere, and has always been universal according to the Qur'an. If this is true,then Muslim intolerance for other beliefs is evidence that they themselves have, at the moment, forgotten the vision revealed in the Qur’an.
The Kafir, and the infidel, variously indicated in the Qur'an as people who are not the follower of any religion, or followers of idolatry, or people who have gone astray. Certainly it is clear from the Qur'an that at least in the case of Christians, and Jews, the same God is recognized, and the religions Islamically legitimate, even if considered much less perfect than Islam. Qur'anic unbelievers (of which I as an agnostic am a member) disbelieve the truth of all religions, and disbelieve all Scriptures as of divine revelation. However, I am not a disbeliever to the extreme of active opposition to the practice of any or all religions- I believe in "live and let live", which has among my Muslim friends most always given me a "pass" from some religiously-mandated sanction.
The Qur’an confirms, or alludes to the truth of all religions in several verses, and in several faoundational verses affirms and presents to the world a Prophet among us, here to confirm the truth of all that was revealed before, through Prophets shared by all 3 Abramic faiths. Muhammed said that "Kafir" was not to be applied to those who say “Salam” to the Muslims. Remember, Muhammed had allies among the "unbelievers" even after Islam had triumphed in Arabia, and Muhammed honored his treaties. It was righteous conduct and orderly commerce, much more than the sword, that sparked the amazing expansion of Islam.
I'm not going to go digging for Qur'anic verses at this point to support the idea that Islam teaches tolerance, even to the point that foreign missionaries are tolerated within many "Islamic" countries (that's another topic, because I doubt the literal existence of one).
I have never seen in the Qur'an anything expressing your assertion "you may not degrade Islam by offering other religion". If I'm wrong, please show me the truth. Salaam.
