Gandhi stated his belief that "Ahimsa is in Hinduism, it is in Christianity as well as in Islam." He added, "Nonviolence is common to all religions, but it has found the highest expression and application in Hinduism (I do not regard Jainism or Buddhism as separate from Hinduism)." When questioned whether violence and non-violence is both taught in Quran, he stated, "I have heard it from many Muslim friends that the Koran teaches the use of non-violence. (... The) argument about non-violence in the Holy Koran is an interpolation, not necessary for my thesis."
