البخارى reports from (سهل ابن سعد (رضى الله عنه said that, (رسول الله (صلى الله عليه و سلم said that (English translation), “70,000 or seven hundred thousand of my Ummah will enter Jannah; the first of them will not enter until the last of them does so, and their faces will look like the full moon (happy and bright)“. (Refer: فتح البارى - 6/319)
Jannah (جنّة) is something which Allaah has prepared for the people who believed in Him the way He taught through His Messenger and lived their lives being His slave until they breath their last. It’s something which Allaah expects from human being, that’s why He created this huge miraculous place as a reward for His slaves. Since Allaah is our Creator, therefore its He who knows what things we aspire for as human beings.
Everything which human being desires in this world and the things which they will desire in the Jannah, those things are already available in the Jannah الحمد الله. Allaah talks about His created Jannah in His un-created Qur’aan (His words) and (رسول الله (صلى الله عليه و سلم talked a lot about this place, which means it’s something we cannot take for-granted. The only way to attain the Jannah is with His mercy and with the pleasure of Allaah and through His total obedience and by having the ‘Master-Slave‘ relationship with Allaah, The Most High.
