1. Jannah

Jannah (plural: Jannat), lit. "garden", is the final abode of the righteous and the Islamic believers, but also the Garden of Eden, where Adam and Hawwā (Eve)  dwelt.

Firdaws is the literal term meaning paradise, but the Quran generally uses the term Jannah symbolically referring to paradise. However "Firdaws" also designates the highest layer of heaven.

In contrast to Jannah, the words Jahannam, Dozukh, and Nār are used to refer to the concept of Hell.

There are many words in the Arabic language for both Heaven and Hell and those words also appear in the Quran and Hadith. Most of them have become part of the Islamic traditions.

Jannah is often compared to Christian concepts of Heaven.

2. Heaven and Jannah

While Jannah in the Quran is often translated as "Heaven" in the sense of an abode where believers are rewarded in afterlife, sama (usually pl. samawat) is also translated as "heaven" in the sense of the sky, sometimes referred to as "seven firmament" (2:29) or "seven strong" (78:12).

The 7 layers of heaven are thought to be analogous to the 7 layers of Jahannam (hell).

Some sources connect the two in some way:

According to Sufi cosmology, Paradise is often depicted over the 7 heavens, between the 8th and the 9th heaven.

In some modern interpretations, based on Surah 21:30 and 67:5, the lowest heaven is also interpreted as the observable universe, with the other 6 heavens beyond, once were a mess together with the earths and later expanded.

3. Images and descriptions of Jannah

The Paradise is described as surrounded by 8 principal gates, each level generally being divided into a 100 degrees guarded by angels (in some traditions Ridwan).

The highest level is known as Firdaws (sometimes called Eden) or Illiyin.

Entrants will be greeted by angels with salutations of peace or Salāmun Alaykum. Furthermore, paradise is considered to be "as vast as the heavens and the earth".

In the Quran, "the Garden" is described with material delights, such as beautiful maidens, precious stones, delicious foods, and constantly flowing water - the latter especially appealing to the desert dwelling Arabs, who spend most of their life in arid lands.

The Islamic texts describe life for its immortal inhabitant as one that is happy - without hurt, sorrow, fear or shame - where every wish is fulfilled.

Traditions relate that inhabitants will be of the same age (33 years), and of the same standing.

Their life is one of bliss including wearing sumptuous robes, bracelets and perfumes as they partake in exquisite banquets served in priceless vessels by immortal youths (Hūrī), as they recline on couches inlaid with gold or precious stones.

According to Muslim belief, everything one longs for in this world will be there in Paradise.

They will eat delicious food and drink, and every bowl will have a new taste. They will take eructation which will digest the food and there will be perfumed sweating for the digestion of water.

Inhabitants will rejoice in the company of their parents, spouses, and children (provided they were admitted to paradise) - conversing and recalling the past.

The food in Jannah never rotting and so delicious it will make any person on earth live without feeling hunger forever.

The dwellings for inhabitants will be pleasant, with lofty gardens, shady valleys, fountains scented with camphor or ginger; rivers of water, milk, honey and pure drinks; delicious fruits of all seasons without thorns;

One day in paradise is considered equal to a thousand years on earth.

Palaces are made from bricks of gold, silver, pearls, among other things. Traditions also note the presence of horses and camels of "dazzling whiteness", along with other creatures.

Large trees whose shades are ever deepening, mountains made of musk, between which rivers flow in valleys of pearl and ruby.

The names of 4 rivers are Saihan (Syr Darya), Jaihan (Amu Darya), Furat (Euphrates) and Nil (Nile).

Salsabīl is the name of a spring that is the source of the rivers of Rahma (mercy) and al-Kawthar (abundance).

Sidrat al-Muntaha is a tree that marks the end of the 7th heaven, the boundary where no creation can pass and beyond which is the Throne of Allah.

In spite of the goodly dwellings given to the inhabitants of paradise, the approval of God and nearness to him is considered greater:

According to the Quran, God will bring the elect near to his throne (‘arsh), a day on which "some faces shall be shining in contemplating their Lord."

The vision of God is regarded as the greatest of all rewards, surpassing all other joys. The true beauty of paradise is also understood as the joy of beholding God, the creator.

Besides the material notion of the paradise, those descriptions are also interpreted as allegories, explaining the state of joy people will get.

For some theologians, seeing God is not a question of sight, but of awareness of God’s presence. The Persian theologian al-Ghazali said:

This life belongs to the world of earth and the world of visibility; the hereafter belongs to the world of transcendental and the world of beings.

By this life I understand your state before death, by hereafter I understand your state after death ...

However, it is impossible to explain the world of beings in this life by any other means than allegories.

4. Inhabitants of Jannah

According to the Quran, the basic criterion for salvation in the afterlife is the belief in the Oneness of God (Tawhīd), Angels of God, revealed books of God, all messengers of God, as well as Repentance to God, and doing Good Deeds.

Though one must do good deeds and believe in God, salvation can only be attained through God's judgment.

Regarding salvation from hell, according to hadith literature, Muhammad () said,

Surely a time will come over hell when its gates shall be blown by wind, there shall be none in it, and this shall be after they have remained therein for many years.”

Still in the Hadith literature, Muhammad () is reported to have said,

" Allah will bring out people from the Fire and admit them into Paradise."

Otherwise some hadiths indicate, that the majority of mankind will not access heaven. According to Sunni Islam, a Muslim, even if condemned to hell, will eventually enter Heaven.

As in life there are many trials which one must face. This is also a condition individuals must encounter in order to enter Jannah:

Or do ye think that ye shall enter the Garden (of bliss) without such (trials) as came to those who passed away before you?

They encountered suffering and adversity, and were so shaken in spirit that even the Messenger and those of faith who were with him cried: "When (will come) the help of Allah?"

Ah! Verily, the help of Allah is (always) near!

 -  Qur'an, surah 2 (al-Baqarah), ayah 214

Did ye think that ye would enter Heaven without Allah testing those of you who fought hard (In His Cause) and remained steadfast?

 -  Qur'an, surah 3 (Al-i-Imran), ayah 142

5. Non-Muslims in Jannah

There are different opinions among scholars in regard whether Non-Muslims could enter Jannah. Some Muslims and Islamic scholars argued Surah 2:62 indicates Jannah is not exclusively for Muslims:

Indeed, those who believed and those who were Jews or Christians or Sābians - those who believed in Allah and the Last Day and did righteousness - will have their reward with their Lord, and no fear will there be concerning them, nor will they grieve. /2:62/

On the other hand, other scholars hold this verse is abrogated by Surah 3:85 and just applied until the arrival of Muhammad ().

For example, before Jesus was born, Jewish will enter Jannah alike Christians, who lived before Muhammad () enter Jannah, but every religious group needs to accept the newest prophet.

And whoever desires other than Islam as religion - never will it be accepted from him, and he, in the Hereafter, will be among the losers.3:85

Scholars like Ibn Arabi did not hold the first to be abrogated by the latter, since "Islam" in this context, does not apply to Islam as a religious tradition, but to "submission".

al-Ghazali distinguished between the "saved" and "those who will attain success". Therefore, righteous Non-Muslims will neither enter hell nor Jannah, but will stay in Araf.

Further those, who regard Jannah as exclusively for Muslims argue, that Islam is the "completed" and "perfected" religion and it is necessary to believe in the whole teaching of God, the prophets and the angels that just can be done by a Muslim.

According to the Islamic theologian Suleyman Ates, Muslims had made a mistake Jewish and Christians made before by claiming paradise being exclusive for Muslims:

Further he states, that those who believes in God without associating any partners with Him, believes in the hereafter without any doubt and do good and useful deeds can enter paradise, conditions several religions offer.

He also refers to the Quran 5:66 that there are good and bad people among any religion, and even not all Muslims may enter paradise.

Finally, most scholars agree that Non-Muslims who did not hear the message of Islam and Non-Muslims who died in childhood are eligible for Jannah as well:

… And We never punish until We have sent a Messenger (to give warning).17:15

6. Number of people who will enter Jannah

Several precise numbers are mentioned in the hadith literature regarding the extremely high standards required to qualify for Jannah:

Initially, a select elite group of 70,000 people from the followers of Muhammad () will enter Jannah without any accountability of their sins.

After the above group, only 1 out of 100 people from the rest of humanity (Muslim and Non-Muslim) would qualify for Jannah.

It is understood that despite this small percentage, the actual number of people who would make it to Jannah would be higher, as Allah would forgive the sins of many people, allowing them to enter Jannah as well.
