Assalamu ‘Alaikum,
As with the rest of the world I am saddened by the sudden death of Michael Jackson. The speculation as to whether he died a Muslim or not continues and remains to be seen whether he gets a Muslim burial or a Christian one.
The following is a link to some words from Imam Zaid Shakir on his passing:

Statement from Dawud Wharansby Ali on his own blog:

And tribute from Yusuf Islam here:

Brother Yahya Birt has just had confirmation that Dawud Wharansby Ali was not present at the alleged Shadah taken by Michael Jackson, neither was Yusuf Islam or Idris Phillips.
