tirmidhi:3292Abū Kurayb > ʿAbdah b. Sulaymān And ʿAbd al-Raḥīm b. Sulaymān > Muḥammad b. ʿAmr > Abū Salamah > Abū Hurayrah

“Allah said: ‘I have prepared for My righteous worshippers, what no eye has seen, nor ear has hear, and no human heart has conceived.’ So recite if you wish: No person knows what is kept hidden for them of delights of the eyes as a reward for what they used to do. And in Paradise there is a tree under whose shade a rider can travel for one hundred years without stopping. Recite if you wish: And in shade extended. And the space occupied by a whip in Paradise is better than the world and whatever is in it. Recite if you wish: And whoever is removed away from the Fire and admitted to Paradise, he indeed is successful. The life of this world is only the enjoyment of deception.”  

Abū ʿĪsá said that this Ḥadīth is Ḥasan-Ṣaḥīḥ.
الترمذي:٣٢٩٢حَدَّثَنَا أَبُو كُرَيْبٍ حَدَّثَنَا عَبْدَةُ بْنُ سُلَيْمَانَ وَعَبْدُ الرَّحِيمِ بْنُ سُلَيْمَانَ عَنْ مُحَمَّدِ بْنِ عَمْرٍو حَدَّثَنَا أَبُو سَلَمَةَ عَنْ أَبِي هُرَيْرَةَ قَالَ قَالَ

رَسُولُ اللَّهِ ﷺ يَقُولُ اللَّهُ أَعْدَدْتُ لِعِبَادِيَ الصَّالِحِينَ مَا لاَ عَيْنٌ رَأَتْ وَلاَ أُذُنٌ سَمِعَتْ وَلاَ خَطَرَ عَلَى قَلْبِ بَشَرٍ وَاقْرَءُوا إِنْ شِئْتُمْ ( فَلا تَعْلَمُ نَفْسٌ مَا أُخْفِيَ لَهُمْ مِنْ قُرَّةِ أَعْيُنٍ جَزَاءً بِمَا كَانُوا يَعْمَلُونَ ) وَفِي الْجَنَّةِ شَجَرَةٌ يَسِيرُ الرَّاكِبُ فِي ظِلِّهَا مِائَةَ عَامٍ لاَ يَقْطَعُهَا وَاقْرَءُوا إِنْ شِئْتُمْ ( وظِلٍّ مَمْدُودٍ ) وَمَوْضِعُ سَوْطٍ فِي الْجَنَّةِ خَيْرٌ مِنَ الدُّنْيَا وَمَا فِيهَا وَاقْرَءُوا إِنْ شِئْتُمْ ( فمَنْ زُحْزِحَ عَنِ النَّارِ وَأُدْخِلَ الْجَنَّةَ فَقَدْ فَازَ وَمَا الْحَيَاةُ الدُّنْيَا إِلاَّ مَتَاعُ الْغُرُورِ )

“Allah says: ‘I have prepared for My righteous slaves that which no eye has seen, no ear has heard, and it has never crossed the mind of man.’”  

ابن ماجة:٤٣٢٨حَدَّثَنَا أَبُو بَكْرِ بْنُ أَبِي شَيْبَةَ حَدَّثَنَا أَبُو مُعَاوِيَةَ عَنِ الأَعْمَشِ عَنْ أَبِي صَالِحٍ عَنْ أَبِي هُرَيْرَةَ قَالَ

قَالَ رَسُولُ اللَّهِ ﷺ يَقُولُ اللَّهُ ﷻ أَعْدَدْتُ لِعِبَادِيَ الصَّالِحِينَ مَا لاَ عَيْنٌ رَأَتْ وَلاَ أُذُنٌ سَمِعَتْ وَلاَ خَطَرَ عَلَى قَلْبِ بَشَرٍ قَالَ أَبُو هُرَيْرَةَ وَمِنْ بَلْهَ مَا قَدْ أَطْلَعَكُمُ اللَّهُ عَلَيْهِ اقْرَءُوا إِنْ شِئْتُمْ {فَلاَ تَعْلَمُ نَفْسٌ مَا أُخْفِيَ لَهُمْ مِنْ قُرَّةِ أَعْيُنٍ جَزَاءً بِمَا كَانُوا يَعْمَلُونَ } قَالَ وَكَانَ أَبُو هُرَيْرَةَ يَقْرَؤُهَا مِنْ قُرَّاتِ أَعْيُنٍ  

قَوْلُهُ تَعَالَى: {فَمَنْ زُحْزِحَ عَنِ النَّارِ وَأُدْخِلَ الْجَنَّةَ فَقَدْ فَازَ} [آل عمران: 185]

الكبرى للنسائي:١١٠١٩أَخْبَرَنَا مُحَمَّدُ بْنُ حَاتِمِ بْنِ نُعَيْمٍ أَخْبَرَنَا سُوَيْدٌ أَخْبَرَنَا عَبْدُ اللهِ عَنْ شَرِيكٍ عَنْ مُحَمَّدِ بْنِ عَمْرٍو عَنْ أَبِي سَلَمَةَ عَنْ أَبِي هُرَيْرَةَ
