So a guy decided to make a video mockery of me on YouTube - this is my response.
This is exactly how all Muslims should respond to such examples of hatred and idiocy.
As the great Imam Al-Shāfi'ī would say "I have never debated an knowledgeable person, except I defeated him with my knowledge. While I have never debated an ignorant, except he defeated me with his ignorance".
Allah also teaches us in the Quran 3:186:
"And you will surely hear from those who were given the Scripture before you and from those who associate others with Allah much abuse. But if you are patient and fear Allah - indeed, that is of the matters [worthy] of determination."
