Hello friend greetings to you, hope you are doing well and good there.

You have said that as a devout Muslim, you have faith in the existence of a final day of life. That final day is called Judgment day or Doom's day. It will be the end of this world. As a Muslim we all believe on both Heaven and Hell and it will be decided on judgement day where God will send a person.

I wish you very best of luck in this contest.
