Interfaith is a Humiliation of Islam

 

Mujajjid Alf e Thani rahimahullah said, "The honor of Islam is dependent upon abasing kufr and the people of kufr. Those who honor the people of kufr are humiliating Islam. Honoring the people of kufr is not confined to a display of honor or giving them a prominent position in a meeting. It also refers to accommodating them in one's gatherings, socializing with them, and enjoying discussions with them. 

Allah Ta'ala says that the disbelievers are His enemies and the enemies of His beloved Rasul. Therefore, interacting with these enemies of Allah and His Rasul, and loving them is a major sin." - Maktub 163 

Note: If interacting and socializing with disbelievers is a major sin, then what can be said of interfaith? We seek the protection and forgiveness of Allah Ta'ala from the blasphemy and polytheism of interfaith.
