Jackson, who was raised a Jehovah's Witness, reportedly decided to convert after discussing religion with a music producer and songwriter on his new album both of whom were converts to Islam, says reports.
"They began talking to him about their beliefs, and how they thought they had become better people after they converted. Michael soon began warming to the idea," a source said. "An Imam was summoned from the mosque and Michael went through the shahada, which is the Muslim declaration of belief. Jacko rejected an alternative name, Mustafa meaning the chosen one," the source added.
Brit singer Yousef Islam, 60, who was called Cat Stevens until he famously converted, turned up to help Jacko celebrate. Meanwhile, Jackson is due to give evidence in court next week after being sued by Sheikh Abdulla bin Hamad Al Khalifa, second son of the King of Bahrain.
Sheikh Abdulla, who is seeking 7 million dollars, claims he helped support the cash-strapped Jackson in the aftermath of his child molestation trial. Abdulla claims Jackson promised to pay back the money, while Jackson says he thought it was a gift. Jackson is expected to give evidence to a London court via video link from LA.
