Description of Paradise in the Qur'an:
Janna (Paradise, Heaven) is called by eight names in the Qur'an: Jannatu al-Khuld, Darul as-Salam, Darul al-Qarar, Jannatu al-`Adn, Jannatu al-Ma`wa, Jannatu an-Na`im, `Illiyin, and Jannatu al-Firdaus. Janna is the Arabic word for "garden."
They have been translated into English as: paradise, a garden on high, a home that will last, garden of eternity, garden of everlasting bliss, gardens of delight, home of peace, home of the righteous, etc.
The Prophet Muhammad is quoted as saying that everyone will see God on the Day of Resurrection, as easily as one can see the sun when there are no clouds.
There will be no sickness, pain, sadness or death there. The Prophet Muhammad said that there are things in Paradise "which no eye has seen no ear has heard and no human mind has thought of."
Descriptions of Paradise in the Qur'an:
Sura (chapter) 2:82: "But those who have faith and work righteousness, they are companions of the Garden: Therein shall they abide (For ever)."
3:133: "Be quick in the race for forgiveness from your Lord, and for a Garden whose width is that (of the whole) of the heavens and of the earth, prepared for the righteous."
3:185: "Every soul shall have a taste of death: And only on the Day of Judgment shall you be paid your full recompense. Only he who is saved far from the Fire and admitted to the Garden will have attained the object (of Life): For the life of this world is but goods and chattels of deception."
18:107: "As to those who believe and work righteous deeds, they have, for their entertainment, the Gardens of Paradise."
39:73: "And those who feared their Lord will be led to the Garden in crowds: until behold, they arrive there; its gates will be opened; and its keepers will say: 'Peace be upon you! well have ye done! enter ye here, to dwell therein'."
39:74: "They will say: 'Praise be to God, Who has truly fulfilled His Promise to us, and has given us (this) land in heritage: We can dwell in the Garden as we will: how excellent a reward for those who work (righteousness)!' "
47:15: "(Here is) a Parable of the Garden which the righteous are promised: in it are rivers of water incorruptible; rivers of milk of which the taste never changes; rivers of wine, a joy to those who drink; and rivers of honey pure and clear. In it there are for them all kinds of fruits; and Grace from their Lord...."
Sura 56:1-40 of the Qur'an deals in depth with the Day of Judgment and the rewards that await persons who have led a good life. 56:15-21: "[They will sit] on gold-encrusted thrones of happiness, reclining upon them, facing one another in [love]. Immortal youths will wait upon them with goblets, and ewers, and cups filled with water from unsullied springs by which their minds will not be clouded and which will not make them drunk; and with fruit of any kind that they choose, and with flesh of any fowl that they may desire."
56:22-26: "And [accompanying them will be their] companions pure, most beautiful of eye, like unto pearls hidden in their shells. [This will be] a reward for what they did [during life]. No empty talk will they hear there, nor any call to sin, but only the tiding of inner soundness and peace."
56:27-33: "Now as for those who have attained to righteousness- what of those who have attained to righteousness? [They too will find themselves] admist fruit-laden lote-trees, and acacias flower-clad, and shade extended, and waters gushing, and fruit abounding, never-failing and never out of reach."
56:34-37: "And [with them will be their] spouses, raised high; for behold, We shall have brought them into being in a life renewed, having resurrected them as virgins, full of love, well matched to those who have attained to righteousness"
Surah 55 discusses the presence of "húr." They have most commonly been considered to be Houris -- beautiful virgins: 55:70: "In them will be fair [Maidens], good, beautiful."
55:72: "Maidens restrained [as to their glances], in [goodly] pavilions."
55:74: "Whom no man or Jinn before them has touched."
Others have interpreted the "húr" to be "the fruits of the good deeds" that a person has performed while alive. They are unique to Paradise and not like anything experienced on Earth. 6 Surah 44:51-55 and 52:17-20 state that the men in Paradise will enter marriage with the Houris.
Jinns are living entities that God created from "a smokeless flame of fire." 5 They are invisible to the human eye but marry, produce children, eat, drink, and die like all other creatures in the universe." 7,8
In his commentary on Surah 55:72, Ibn Kathir (d. 1373 CE) stated: "The Prophet Muhammad was heard saying: 'The smallest reward for the people of paradise is an abode where there are 80,000 servants and 72 wives, over which stands a dome decorated with pearls, aquamarine, and ruby, as wide as the distance from Al-Jabiyyah [a Damascus suburb] to Sana'a [Yemen]'." 9
Who is eligible for entry into Paradise:
Entry to Paradise is limited to those who believe in God and his messengers, and who have led a good life on earth. In the Qur'an:
Surah 2:25: "And give good news [O Muhammad] to those who believe and do good deeds, that they will have gardens [Paradise] in which rivers flow...."
Surah 4:57: "But those who believe and do good deeds, We will admit them to gardens (Paradise) in which rivers flow, lasting in them forever...."
Surah 57:21: "Race one with another for forgiveness from your Lord and for Paradise, whose width is as the width of the heavens and the earth, which has been prepared for those who believe in God and His messengers...."
Presumably Agnostics, Atheists, Polytheists, and followers of non-Abrahamic religions will be denied access to Paradise because of their lack of belief. So too will be people who have done a preponderance of evil deeds.
