Sayyiduna Abu Hurairah (may Allah be pleased with him) said: The Messenger of Allah (peace and blessings be upon him) said: "In Paradise, there is a tree under whose shade a rider could travel for a hundred years and still not cross it. If you wish, recite: «﴿وَظِلٍّمَمْدُودٍ﴾» (Al-Waqi'ah: 30/56), meaning there are long shades in Paradise."

Brief Explanation
(Commentary on Hadith 2871)
In another narration of Sahih Muslim, it is stated: In Paradise, there is a tree under whose shade a swift, well-prepared (ready) horseman would ride for a hundred years, yet he would not be able to traverse it completely.
In the Noble Qur’an, there is mention of long shades; the hadith has explained this, clarifying just how long that shade will be.
