Heaven is a name that is known by every human being, both Muslims and non-Muslims, as a place full of pleasure. However, only Muslims have the right to live in heaven, as for unbelievers, their place of return is hell.
Allah Ta'ala says,
Indeed, those who disbelieve from among the People of the Book and the polytheists will be in the fire of Hell to abide therein. These are the worst of creation. (6) Indeed, those who believe and do righteous deeds are They are the best of creation. (7) Their reward is with their Lord, the Gardens of Eden, beneath which rivers flow, to abide therein forever. May God be pleased with them and they are pleased with No, that's for whom He feared his Lord (8
"Indeed, the disbelievers, namely the people of the Book and the polytheists (will enter) hell; they remain in it. They are the worst of creatures. Indeed, those who believe and do righteous deeds, they are the best of creatures. Their reward with their Lord is Paradise under which rivers flow, they will remain in it forever. God is pleased with them and they are pleased with Him. That is (the reward) for those who fear their Lord." (QS. Al-Bayyinah: 6-8)
Understanding Heaven
Heaven means a garden in which there are many trees and date palms. Some language scholars say, "It is not called Jannah/paradise in Arabic unless it contains date palms and grapes." Others say that it is called heaven/jannah because the trees in it are thick and their branches provide shade for those beneath them.
Names of Heaven
1. Darussalam (House of Peace)
Allah Ta'ala says,
For them is the abode of peace at their Lord’s side, and He is their guardian wherever they are and what they do.
"For them (provided) Darussalam (heaven) is with their Rabb and He is their Protector because of the righteous deeds they always do." (QS. Al-An'am: 127)
Some scholars say, "It is called darussalam because heaven is a place that is free from dirty things, dangerous things and things that are disliked." Another opinion says it means Darullah, because As-Salam is one of the names of Allah.
2. Jannatul Khuld (Paradise of Eternity)
Allah Ta'ala says,
Say, is that better, or the eternal Paradise which is promised to the righteous? It is for them a reward and a destination.
"Say (Muhammad), "Is such (adzab) good, or the eternal paradise promised to the pious as a reward, and a place of return for them?" (QS. Al-Furqan: 15)
It is called by this name because the inhabitants of heaven remain eternally in heaven, do not move to another place, and do not look for another place other than heaven.
3. Jannatul Ma’wa (Paradise of Refuge)
Allah Ta'ala says,
At the Sidra of the End (14) There is the Garden of Refuge
“(namely) at Sidratul Muntaha. Nearby is a paradise of abode.” (QS. An-Najm: 14-15)
4. Darul Muqamah (House of Resurrection)
Allah Ta'ala says,
And they said, “Praise be to God who has removed from us sorrow. Indeed, our Lord is Forgiving, Most Gracious. (34) Who has granted us the abode of residence out of His bounty. No calamity shall touch us therein, nor shall anyone touch us.” Therein therein is negligence. (35
"And they said, "All praise be to God who has removed sorrow from us. Truly, our Lord is truly Forgiving and Gracious. Who by His grace places us in an eternal place (heaven); in it we do not feel tired nor lethargic". (QS. Fathir: 34-35)
5. Jannatu ‘Adn (Gardens of Eden)
