Sahih Muslim 2827, 2828Book 53, Hadith 9
حَدَّثَنَا إِسْحَاقُ بْنُ إِبْرَاهِيمَ الْحَنْظَلِيُّ، أَخْبَرَنَا الْمَخْزُومِيُّ، حَدَّثَنَا وُهَيْبٌ، عَنْ أَبِي، حَازِمٍ عَنْ سَهْلِ بْنِ سَعْدٍ، عَنْ رَسُولِ اللَّهِ صلى الله عليه وسلم قَالَ " إِنَّ فِي الْجَنَّةِ لَشَجَرَةً يَسِيرُ الرَّاكِبُ فِي ظِلِّهَا مِائَةَ عَامٍ لاَ يَقْطَعُهَا " .
قَالَ أَبُو حَازِمٍ فَحَدَّثْتُ بِهِ النُّعْمَانَ بْنَ أَبِي عَيَّاشٍ الزُّرَقِيَّ، فَقَالَ حَدَّثَنِي أَبُو سَعِيدٍ الْخُدْرِيُّ عَنِ النَّبِيِّ صلى الله عليه وسلم قَالَ " إِنَّ فِي الْجَنَّةِ شَجَرَةً يَسِيرُ الرَّاكِبُ الْجَوَادَ الْمُضَمَّرَ السَّرِيعَ مِائَةَ عَامٍ مَا يَقْطَعُهَا " .
In Paradise, there is a tree under the shadow of which a rider can travel for a hundred years without covering (the distance) completely. This hadith has also been transmitted on the authority of Abu Sa'id al-Khudri that Allah's Apostle (ﷺ) is reported to have said: In Paradise, there is a tree under the shadow of which a rider of a fine and swift-footed horse would travel for a hundred years without covering the distance completely. There would be the pleasure of Allah for the inmates of Paradise and He would never be annoyed with them.
