This Thursday at 4 p.m. will be an unforgettable moment for Muslims in Michigan. Religious leaders from both the Shia and Sunni communities and members of the Council of Islamic Organizations of Michigan will meet at the Islamic House of Wisdom in Dearborn Heights to sign a Muslim Code of Honor. The code commits its signers to reject extremism in all its forms.
Hundreds of great scholars from Shia and Sunni backgrounds have struggled to unify Muslims.
That's why there is no place for calling others nonbelievers when they do believe. All Muslims regardless of their different interpretations of the khelafa (successorship of the prophet) share a belief in the unity of God, the prophethood of Mohammad, the authenticity of the Quran and the certainty of the Day of Resurrection. There is no disagreement over the principles of prayer, Ramadan fast, charity and pilgrimage to Mecca.
