Greetings

You are right dear friend its a short stay on earth and itvwill be ended soon and then after the judgment real life will be started.

In the Holy Qur'an not once, many times heaven and hell ie our paradise and hell have been mentioned. Our time in this world is very short. We never know who will call when. We must leave this world.

Many times explained in Holy Quran so there is no doubt about the heaven and hell in our heart.

Good luck
