Abu Hurairah (May Allah be pleased with him) said:
The Messenger of Allah (ﷺ) said, "Allah, the Exalted, has said: 'I have prepared for my righteous slaves what no eye has seen, no ear has heard, and the mind of no man has conceived.' If you wish, recite:'No person knows what is kept hidden for them of joy as a reward for what they used to do."' (32:17)[Al-Bukhari and Muslim].
