Sahih al-Bukhari, Hadith 3244 ⓘ
Narrated Abu Huraira: Allah's Messenger said, "Allah said, "I have prepared for My Pious slaves things which have never been seen by an eye, or heard by an ear, or imagined by a human being." If you wish, you can recite this Verse from the Holy Qur'an:--"No soul knows what is kept hidden for them, of joy as a reward for what they used to do." (32.17)
حَدَّثَنَا الْحُمَيْدِيُّ، حَدَّثَنَا سُفْيَانُ، حَدَّثَنَا أَبُو الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ ـ رضى الله عنه ـ قَالَ قَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم " قَالَ اللَّهُ أَعْدَدْتُ لِعِبَادِي الصَّالِحِينَ مَا لاَ عَيْنَ رَأَتْ، وَلاَ أُذُنَ سَمِعَتْ، وَلاَ خَطَرَ عَلَى قَلْبِ بَشَرٍ، فَاقْرَءُوا إِنْ شِئْتُمْ {فَلاَ تَعْلَمُ نَفْسٌ مَا أُخْفِيَ لَهُمْ مِنْ قُرَّةِ أَعْيُنٍ }".
