Riyad as-Salihin, Book 1, Hadith 443 (In-Book)

Abu Hurairah (May Allah be pleased with him) reported: Messenger of Allah 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].

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)‏‏)‏‏.‏
