Abu Huraira reported that Allah's Apostle (ﷺ) said:Allah, the Exalted and Glorious, said: I have prepared for My pious servants which no eye (has ever) seen, no ear has (ever) heard and no human heart has ever perceived those bounties leaving apart (those bounties) about which Allah has informed you.
حَدَّثَنِي هَارُونُ بْنُ سَعِيدٍ الأَيْلِيُّ، حَدَّثَنَا ابْنُ وَهْبٍ، حَدَّثَنَا مَالِكٌ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ " قَالَ اللَّهُ عَزَّ وَجَلَّ أَعْدَدْتُ لِعِبَادِيَ الصَّالِحِينَ مَا لاَ عَيْنٌ رَأَتْ وَلاَ أُذُنٌ سَمِعَتْ وَلاَ خَطَرَ عَلَى قَلْبِ بَشَرٍ ذُخْرًا بَلْهَ مَا أَطْلَعَكُمُ اللَّهُ عَلَيْهِ " .
