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

You have strong believe on Heaven and Hell. You have said that, We must leave this world one day, and our time in this world is too short. Very true my friend. Know one knows when we leave this world. You have given the references of the Holy Quran, In the Holy Qur'anmany times heaven and hell have been mentioned. Yes this is true and it's repeat in the Quran many times.

I wish you very best of luck in this contest.
