In Islamic tradition, seven heavens are described above the earth in the Qur’an and hadith. The Arabic expression samāwāt commonly refers to these layered heavens, which are part of Islamic cosmological and eschatological teachings.
The Qur’an repeatedly speaks of God creating “seven heavens,” including in Qur’an 2:29 and 67:3. The number is therefore a scriptural feature rather than a later popular invention. Islamic sources do not generally treat the seven heavens as identical to the seven planets of modern astronomy.
The Mi'raj narratives describe Muhammad’s ascent through the heavens, where he encounters earlier prophets. These accounts connect the layered cosmos with prophetic history and revelation, although details differ among hadith collections and later interpretations.
The seven heavens should not be confused with the many levels of Jannah or the traditional seven gates of Jahannam. They are cosmic levels or realms in Islamic belief, while paradise and hell concern post-judgment destinations.
