As far as the Jews are concerned
1.During the life of Prophet Muhammad, the Jews in Madina had a synagogue and an educational institute by the name of Bait-Al-Madras. He made sure it was preserved as well as all the Jews attending it were protected.
2.The Prophet of Islam made several treaties with the Jews. Following is an extract of a message that he wrote to form a treaty:
In the name of God, Most Gracious, Ever Merciful. This message is from Muhammad, Messenger of God. Verily, whoever follows us from the Jews shall have the help and the aid; and shall neither be victim of injustice, nor taken vengeance upon. The Jews of the children of Awf are safe with the Faithful. They have their religion and the Muslims theirs and themselves, except those who oppress or sin, they will forfeit themselves and their families. The Jews of Bani Al-Najjar, of Bani Al-Harith, of Bani Saaedah, of Bani Aws and of Bani Belanah are Jews like the others.
As far as the Christians are concerned
1.The Prophet honored the Christians of Najran from Yemen who visited him in his own mosque in Madina. The Christians prayed according to Christian fashion inside the mosque, and the Prophet and his followers prayed in Muslim tradition.
2.The Prophet respected the autonomy of the Christian churches. The nomination and the appointment of bishops and priests was left to the Christian community itself.
3. Prophet Muhammad promoted cooperation between Muslims and Christians in the political arena as well. The prophet selected a non-Muslims and delegated him as his ambassador to Negus, the king of Ethiopia. The name of that ambassador was 'Amr-ibn-Umaiyah-ad-Damri.
4.During the days of the Prophet, there were two super powers, the Persians and the Romans. The Romans adopted Christianity while the Persians adopted atheist beliefs. Those two super powers were at war with each other. During that period, Muslims were a small minority in the Arabian Peninsula. They prayed to Almighty God that the Romans would win the war against the Atheistic forces. The feelings and the beliefs of the Muslims were based on the fact that the Romans were part of the People of the Book. (See Qur'an 30: 1-7)
5.The Prophet sent a message to the Monks of Saint Catherine in Mount Sinai. The English translation of that document is as follows:
This is a message written by Muhammad Ibn Abdullah, as a covenant to those who adopt Christianity, far and near, we are behind them. Verily, I defend them by myself, the servants, the helpers, and my followers, because Christians are citizens; and by Allah! I hold out against anything that displeases them. No compulsion is to be on them. Neither are their judges to be changed from their jobs, nor their monks from their monasteries. No one is to destroy a house of their religion, to damage it, or to carry anything from it to the Muslims' houses. Should anyone take any of these, he would spoil God's covenant and disobey His Prophet. Verily, they are my allies and have my secure charter against all that they hate one is to force them to travel or to oblige them to fight. The Muslims are to fight for them. If a female Christians is married to a Muslim, this is not to take place without her own wish. She is not to be prevented from going to her church to pray. Their churches are to be respected. They are neither to be prevented from repairing them nor the sacredness of their covenants. No one of the nation is to disobey this covenant till the Day of Judgement and the end of the world.
Contemporary Treatment of Non-Muslims
Non-Muslims flourished in the Muslim world in all aspects of life even after the abolition of colonialism. Anywhere a person goes in both the Arab world and the non-Arab Muslim world, he will see Christians and Jews. They have lived freely in the Muslim community and have thrived in the fields of religion, education, economics, politics, health, industry, farming, housing, banking, festivities, and social services.
In several Muslim countries like Jordan, Egypt, Lebanon, Palestine, Syria, Algeria or Sudan, etc. there are a large number of Christians in the highest political levels of the government.
Today there are forces that seem to be propelling a clash of civilizations, but let us build a bridge of understanding and mutual respect through the exploration of commonalities among all civilizations.
