Hofmann was born a Catholic, but converted to Islam in 1980. He studied at Harvard University. His conversion was met with some controversy due to his high profile in the German government. He converted to Islam as a result of what he witnessed in the Algerian War of Independence, his fondness for Islamic art, and what he saw as contradictions in Paulist Christian doctrine.
one of his Quote :
“I began to see Islam with its own eyes, as the unadulterated, pristine belief in the one and only, the true God, Who does not beget, and was not begotten, Whom nothing and nobody resembles … In place of the qualified deism of a tribal God and the constructions of a divine Trinity, the Qur’an showed me the most lucid, most straightforward, the most abstract - thus historically most advanced – and least anthropomorphic concept of God. The Qur’an’s ontological statements, as well as its ethical teachings, impressed me as profoundly plausible, “as good as gold,” so there was no room for even the slightest doubt about the authenticity of Muhammad’s prophetic mission. People who understand human nature cannot fail to appreciate the infinite wisdom of the “Dos and Don’ts” handed down from God to man in the form of the Qur’an.”
