As usual, internet search, filtering out the ones the silly, untrue and such (which is hard) and finally my research eventually paid off.
The song "give thanks to Allah" was actually written and sung by Zain Bhikha, from Johannesburg, Gauteng South Africa, and he has been singing since he won the singing competition in 1994.
From wikipedia:
Zain Bhikha, born August 9, 1974 is a South African Muslim singer-songwriter, who has achieved fame as a performer of nasheed songs. Tied to other prominent Muslims entertainers, including Yusuf Islam and Dawud Wharnsby Ali, Bhikha has collaborated on albums with other artists, and has released several solo albums as well. He has written several religious albums concerning Islam.
Gonna post links regarding about him at the end of the post:
Anyways, regarding the late MJ singing this, the rumour has also reached into the ears of the said Zain Bhikha, and in response to this, he posted the following:
[quote from website]
The reason I bring all this up is merely because since before his death and quite amplified now after, I have been inundated with e-mails and calls from people, organisations and the media asking me to clarify whether a song called “Give Thanks to Allah” was sung by Micheal Jackson or myself. This rumour started a while ago and has been circulating on the internet ever since.
So, to clarify, Micheal Jackson never sang this song. I wrote and recorded “Give Thanks to Allah” as a simple childrens song many years ago and it has been released on various independant albums since.[end quote]
So as you can see and explain by Zain Bhikha, the late MJ NEVER sung that song. I also read in various sites/forum saying Zain and MJ has nearly similar voice thus explaining the confusion.
Before ending, I would like to point out whoever has that song must keep in mind to whom the credit is due. Zaid Bhikha is the songwriter and singer of "Give Thanks to Allah" and what I have been reading is that his songs are educational and inspiring, and has an islamic theme to it.
