that the Prophet ﷺ said: "Allah Most High said: 'I have prepared for My righteous worshipers what no eye has seen, no ear has heard, and no human heart has conceived.'" And that is testified to in Allah's [the Mighty and Sublime] Book: No person knows what is kept hidden for them of delights of the eyes (32:17).
النَّبِيَّ ﷺ قَالَ قَالَ اللَّهُ تَعَالَى أَعْدَدْتُ لِعِبَادِي الصَّالِحِينَ مَا لاَ عَيْنٌ رَأَتْ وَلاَ أُذُنٌ سَمِعَتْ وَلاَ خَطَرَ عَلَى قَلْبِ بَشَرٍ وَتَصْدِيقُ ذَلِكَ فِي كِتَابِ اللَّهِ ﷻ ( فلاَ تَعْلَمُ نَفْسٌ مَا أُخْفِيَ لَهُمْ مِنْ قُرَّةِ أَعْيُنٍ جَزَاءً بِمَا كَانُوا يَعْمَلُونَ ) قَالَ هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ
