I witnessed a gathering with the Messenger of Allah ﷺ in which he described Paradise until he finished. Then at the end of his discourse he said, "In it is what no eye has seen, no ear has heard, and what has never crossed the heart of any human being." Then he recited this verse, "Their sides forsake their beds, calling upon their Lord in fear and hope, and they spend from what We have provided them. And no soul knows what has been hidden for them of comfort for the eyes as a reward for what they used to do." [Sajdah 32:16–17]
شهدت من رسول الله ﷺ مجلسا وصف فيه الجنة حتى انتهي، ثم قال في آخر حديثه: فيها ما لا عين رأت ولا أذن سمعت، ولا خطر على قلب بشر، ثم اقترأ هذه الآية: {تتجافى جنوبهم عن المضاجع يدعون ربهم خوفا وطمعا ومما رزقناهم ينفقون فلا تعلم نفس ما أخفي لهم من قرة أعين جزاء بما كانوا يعملون}
Muslim narrated it in the Book of Paradise and Its Bliss (2825), through several routes, from Ibn Wahb, who said, Abu Sakhr narrated to me, that Abu Hazim told him, saying, I heard Sahl bin Saad, and he related it.
