Compiled by Imam Yahya ibn Sharaf al-Nawawi
وعن أبي هريرة، رضي الله عنه ، أن رسول الله صلى الله عليه وسلم قال" لو يعلم المؤمن ما عند الله من العقوبة، ما طمع بجنته أحد، ولو يعلم الكافر ما عند الله من الرحمة، ما قنط من جنته أحد” ((رواه مسلم)).
Messenger of Allah (ﷺ) said, "If a believer had full knowledge of the chastisement of Allah, none would covet His Jannah; and were an infidel to know the Mercy Allah has, none would despair of His Jannah".[Muslim].
