ASSALAM O ALAIKUM!
Heaven: The word โJannahโย has been derived from the word โJannโ which means โto hide somethingโ.
Jannah (Heaven) is so called because its land has been hidden by the dense gardens & orchards.
According to Hazrat Ibn-e-Abbas ??? ????? ???? ??? , The word โJannahโย is in plural terms because there are seven (7) Heavens:
* Jannat-ul-Firdaus
* Jannat-Adan
* Jannat-ul-Nayeem
* Daar-ul-Khuld
* Jannat-ul-Mavaโ
* Dar-ul-Salaam
* Aliyyeen
According to Moโaz Bin Jabal ??? ????? ???? ???ย , Muhammad ?? ????? ???? ????ย said: โVerily, there are 200 Levels (??????) in Heaven & there is the distance of Earth & Sky between two of the consective levels. The highest grade is in Jannat-ul-Firdaus, above which is Arsh of Rehman & the Rivers of Jannah originate from this place. Thus whenever you raise your hands, pray for Jannat-ul-Firdaus to Allah ?????. (Trimidhi)
Any mistake, on my part, if found, may please be forgiven.
JAZAAK ALLAH!
