Religious conversion is the adoption of a set of beliefs identified with one particular religious denomination. Thus "religious conversion" would describe the abandoning of adherence to one denomination and affiliating with another. People convert to a different religion for various reasons, including active conversion by free choice due to a change in beliefs, secondary conversion, deathbed conversion, conversion for convenience, marital conversion, and forced conversion.
What is a Hindu?

Hindu refers to any person who regards themselves as culturally, ethnically, or religiously adhering to aspects of Hinduism. It has historically been used as a geographical, cultural, and later religious identifier for people indigenous to the Indian subcontinent.

Early Islam or the history of Islam is believed, by most historians to have originated with Muhammad's mission in Mecca and Medina at the start of the 7th century CE. Although Muslims regard this time as a return to the original faith passed down by the Abrahamic prophets, such as Adam, Noah, Abraham, Moses, David, Solomon, and Jesus, with the submission (Islam) to the will of God. According to the traditional account, the Islamic prophet Muhammad began receiving what Muslims consider to be divine revelations in 610 CE, calling for submission to the one God, preparation for the imminent Last Judgement, and charity for the poor and needy.
