In Islam, Jannah (Arabic: جَنَّةٍ, romanized: janna, pl. جَنّٰت jannāt, lit. 'garden') is the final and permanent abode of the righteous. According to one count, the word appears 147 times in the Qur'an. Belief in the afterlife is one of the six articles of faith in Sunni and is a place in which "Sunni believers" (Sunni Muminin and Sunni Muminat) will enjoy pleasure, while the unbelievers (Kafir) will suffer in Jahannam. Both Jannah and Jahannam are believed to have several levels.
