Islam

Similar to Jewish traditions such as the Talmud, the Qur'an and Hadith frequently mention the existence of seven samāwāt (سماوات), the plural of samāʾ (سماء), meaning 'heaven, sky, celestial sphere', and cognate with Hebrew shamāyim (שמים). Some of the verses in the Qur'an mentioning the samaawat are 41:12, 65:12 and 71:15. Sidrat al-Muntaha, a large enigmatic Lote tree, marks the end of the seventh heaven and the utmost extremity for all of God's creatures and heavenly knowledge.

One interpretation of "heavens" is that all the stars and galaxies (including the Milky Way) are part of the "first heaven", and "beyond that six still bigger worlds are there," which have yet to be discovered by scientists.

According to Shi'ite sources, Ali mentioned the names of the seven heavens as below:

Still an afterlife destination of the righteous is conceived in Islam as Jannah (Arabic: جنة "Garden " translated as "paradise"). Regarding Eden or paradise the Quran says, "The description of the Paradise promised to the righteous is that under it rivers flow; eternal is its fruit as well as its shade. That is the ˹ultimate˺ outcome for the righteous. But the outcome for the disbelievers is the Fire!" Islam rejects the concept of original sin, and Muslims believe that all human beings are born pure. Children automatically go to paradise when they die, regardless of the religion of their parents.

Paradise is described primarily in physical terms as a place where every wish is immediately fulfilled when asked. Islamic texts describe immortal life in Jannah as happy, without negative emotions. Those who dwell in Jannah are said to wear costly apparel, partake in exquisite banquets, and recline on couches inlaid with gold or precious stones. Inhabitants will rejoice in the company of their parents, spouses, and children. In Islam if one's good deeds outweigh one's sins then one may gain entrance to paradise only through God's mercy. Conversely, if one's sins outweigh their good deeds they are sent to hell. The more good deeds one has performed the higher the level of Jannah one is directed to.

Quran verses which describe paradise include: 13:15, 18:31, 38:49–54, 35:33–35 and 52:17.

The Quran refers to Jannah with different names: Al-Firdaws, Jannātu-′Adn ("Garden of Eden" or "Everlasting Gardens"), Jannatu-n-Na'īm ("Garden of Delight"), Jannatu-l-Ma'wa ("Garden of Refuge"), Dāru-s-Salām ("Abode of Peace"), Dāru-l-Muqāma ("Abode of Permanent Stay"), al-Muqāmu-l-Amin ("The Secure Station") and Jannātu-l-Khuld ("Garden of Immortality"). In the Hadiths, these are the different regions in paradise.
