Abu Hurairah reported that the Messenger of Allah ﷺ said, "Allah has said, 'I have prepared for My righteous servants what no eye has seen, no ear has heard, and what has never crossed the heart of any human being.'"Abu Hurairah added, "Recite if you wish, 'No soul knows what comfort has been hidden away for them as a reward for what they used to do' [Sajdah 32:17]."
عن رسول الله ﷺ قال: قال الله تبارك وتعالى: أعددت لعبادي الصالحين ما لا عين رأت، ولا أذن سمعت، ولا خطر على قلب بشر قال أبو هريرة: اقرؤوا إن شئتم {فلا تعلم نفس ما أخفي لهم من قرة أعين}
Bukhari narrated it in the tafsir (4779), and Muslim in Paradise and the description of its bliss (2824), both of them through Sufyan, from Abu Zinad, from Araj, from Abu Hurairah, who mentioned it. The wording given here is Bukhari's, and Muslim's wording is similar.
