Al-Manea gave a fatwa (religious advisory opinion), reported by Al-Anba’ Kuwaiti newspaper, stating that Muslims may pray in Shiite or Sufi mosques, churches or synagogues. He noted that all lands belong to God, and cited the Prophet’s words: “The earth has been made a place of prostration and a means of purification for me.”
Al-Manea said that Islam is a religion of coexistence not of violence, and noted that Muslims cannot have differences in the basic principles of Aqidah (creed) of Islam, but they may differ in the branches.
Concerning dealing with non-Muslims, Al-Manea cited an occasion when the Prophet received a delegation of Christians from Najran in his mosques, and he allowed them to perform their own prayer facing Jerusalem. Al-Manea also cited other sayings of the Prophet which reflected his kindness and mercy with non-Muslims.
Al-Manea stressed that Islam spread in many countries, such as Indonesia and Malaysia, because of the good manners of Muslim merchants, which attracted the citizens of these countries to embrace Islam.
Al-Manea stated that the Prophet explained all aspects of good and warned of everything evil. Al-Manea called upon Muslims to be thankful to God for the blessing of faith and warned against rushing into giving fatwas.
The office of Al-Manea issued a statement 10 years ago stressing that Muslims are allowed to enter churches to look around and gain more knowledge about these places of worship. The statement referred to the incident when Omar bin Al-Khattab, the second Muslim Caliph, refused to pray at the Church of the Holy Sepulchre in Jerusalem because he did not want Muslims to bother Christians in their church. Instead, he prayed in a nearby area, where a mosque was built with the name Omar Mosque. Yet, Omar did not say that Muslims cannot enter churches.
Al-Manea stressed that Muslims “may enter churches to learn about them, and Christians are allowed to enter mosques — except the Grand Mosque in Makkah — and pray in them.”
