The Prophet ﷺ said, "In Paradise there is a tree so vast that a rider could travel in its shade for a hundred years and still not pass beyond it."
عن النبي ﷺ قال: إن في الجنة شجرة يسير الراكب في ظلها مائة عام لا يقطعها.
Bukhari narrated it in the tafsir (4881), and Muslim in the chapter on Paradise (2826:7), both by way of Abu Zinad, from Araj, from Abu Hurairah, as mentioned above. The wording is Bukhari's, for Muslim did not give the wording for this chain but merely referred back to the hadith before it.
