From Hinduism and practicing sorcery, he reverted to Islam

[IslamLife00]

This brother was a Hindu and he was owner of a night club he was getting a lot of money from the club till the night club didn't get him that much money so he went to his Hindu family
(his father is a Hindu priest, his grandfather is also a Hindu priest and he was supposed to be a Hindu priest) which told him to practice sorcery to get money ...
so he did practice sorcery and he started getting money again from the night club for a while till the sorcery stopped working ...he tried again & again but the sorcery is no use anymore ,
this is when he realized that he's not the one in control over things ... so he started looking for the Truth

Say, [O Muḥammad], "It has been revealed to me that a group of the jinn listened (to the Quran) and said (to other jinn), 'Indeed, we have heard an amazing recitation.
It guides to the right guidance, and we have believed in it.
And we will never associate with our Lord anyone.
And Exalted is the Majesty of our Lord: He has taken neither a wife nor a son
And that the foolish among us used to utter about Allah an excessive transgression
And we had thought that humankind and the jinn would never speak about Allah a lie
And there were men from mankind who sought refuge in men from the jinn, so they (the jinn) increased them (those men) in burden
And those (men) thought, just like you (the jinn) thought, that Allah would not resurrect anyone (on Judgement Day)' Al-Jinn 1-5

Say: He is Allah, the One and Only
Allah, the Eternal, the Absolute,
He neither begets nor is born
Nor is there to Him any equivalent. Al-Ikhlas
