The Prophet ﷺ reported that Allah the Exalted says, "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, treasured up and beyond anything you have been shown."Then he recited, "No soul knows what delight of the eyes has been hidden away for them as a reward for what they used to do" [Sajdah 32:17].
عن النبي ﷺ: يقول الله تعالى: أعددت لعبادي الصالحين ما لا عين رأت، ولا أذن سمعت، ولا خطر على قلب بشر، ذخرا بله ما أطلعتم عليه، ثم قرأ: {فلا تعلم نفس ما أخفي لهم من قرة أعين جزاء بما كانوا يعملون} [السجدة: ١٧].
Bukhari narrated it in the tafsir (4780), and Muslim in "Paradise" (4:2824), both through Amash, from Abu Salih, from Abu Hurairah, and he related it.
