عن أبي هريرة رضي الله عنه قال: قال رسول الله صلى الله عليه وسلم: قال الله أعددت لعبادي الصالحين ما لا عين رأت ولا أذن سمعت ولا خطر على قلب بشر فاقرءوا إن شئتم فلا تعلم نفس ما أخفي لهم من قرة أعين (صحيح البخاري، الرقم: 3244)
Hazrat Abu Hurairah (radhiyallahu ‘anhu) reports that Rasulullah (sallallahu ‘alaihi wasallam) mentioned that Allah Ta‘ala has said, “I have prepared for My pious servants such bounties which no eye has ever seen, no ear has ever heard of, and the thought of which has not crossed the heart (i.e. the mind and imagination) of any person.” Rasulullah (sallallahu ‘alaihi wasallam) then said, “If you wish (to find mention of this in the Qur’aan Majeed), then recite the following verse, ‘No person knows what delights of the eye are kept hidden (in store) for them - as a reward for their (good) deeds.’”
Note: In many verses of the Qur’aan Majeed and in various Ahaadith, different bounties of Jannah have been mentioned and described. Hence, the bounties mentioned in this Hadith refer to those bounties which have not been mentioned and described anywhere in the Qur’aan and Hadith.
