Whoever knew Lil Durk practices the Islamic faith? Durk confirmed he was Muslim after retweeting a fan who recently learned about his religion.

This explains why Durk was so angry with Donald Trump’s proposal to ban Muslims from entering the United States.

Trump called for the ban on Muslims entering the country following the deadly Paris Attacks that claimed the lives of at least 130 people and the mass shooting in San Bernardino, CA that killed and injured dozens.

Durk took to Twitter to slam the GOP presidential nominee.

“@realDonaldTrump you fu as hell u won clown of the year,” he wrote.

“Trump’s motives were clarified in a campaign press release that read, “Donald J. Trump is calling for a total and complete shutdown of Muslims entering the United States until our country’s representatives can figure out what is going on.”

Trump defended his words during an interview with CNN Tonight’s Don Lemon.

“I’m doing good for the Muslims,” he said. “Many Muslim friends of mine are in agreement with me. They say, ‘Donald, you brought something up to the fore that is so brilliant and so fantastic.”
