Tawfik Hamid, an Egyptian Islamic scholar, said the following about Islam in Defeat The Third Jihad: From the Heart of a Muslim


We have never had a clear and strong stand against the concept of slavery or wars, to spread our religion and to subjugate others to Islam and force them to pay a humiliating tax called jizia. We ask others to respect our religion while all the time we curse non-Muslims loudly (in Arabic) in our Friday prayers in the mosques….

I have to admit that our current Islamic teaching creates violence and hatred toward non-Muslims. We Muslims are the ones who need to change. Until now we have accepted polygamy, the beating of women by men, and killing those who convert from Islam to other religions…

It is our absolute silence against the terrorists that gives the energy to these terrorists to continue doing their evil acts...

Our religious leaders have to show a clear, and very strong stand against polygamy, paedophilia, slavery, killing those who convert from Islam to other religion, beating of women by men, and declaring wars on non-Muslims to spread Islam.

Then, and only then, do we have the right to ask others to respect our religion.The time has come to stop our hypocrisy and say it openly: We Muslims have to change!.”
