Hadith: In Paradise there is a tree that the rider of a lean swift horse cannot cover (its distance) in one hundred years

عن أبي سعيد الخدري رضي الله عنه عن النبي صلى الله عليه وسلم قال: «إن في الجنة شجرة يسير الراكب الْجَوَادَ الْمُضَمَّرَ السريع مائة سنة ما يقطعها». وروياه في الصحيحين أيضًا من رواية أبي هريرة رضي الله عنه قال: «يسير الراكب في ظلها مئة سنة ما يقطعها».
[صحيح] - [حديث أبي سعيد: متفق عليه. حديث أبي هريرة: متفق عليه]

Abu Sa‘īd al-Khudri (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "In Paradise there is a tree that the rider of a lean swift horse cannot cover (its distance) in one hundred years." Abu Hurayrah (may Allah be pleased with him) reported that the Prophet (may Allah's peace and blessings be upon him) said: "A rider walks in its shade one hundred years without crossing it."
[Authentic hadith] - [Al-Bukhari and Muslim with its two versions]
