What is the aim of circumcision of men in Islam?

Re: What is the aim of circumcision of men in Islam?

any particular reason of adopting the practice?

Islam adopted pretty much every thing from Deen-e-Ibrahimi, except for the things that people innovated later on. Many of the rituals and practices that are part of Islam (including Hajj, Zakat and Roza) came to us from Deen-e-Ibrahimi.
