Mukhtasar Muslim

Sahl bin Sa'd (may Allah be pleased with him) narrates from the Messenger of Allah (peace and blessings be upon him) that he said: In Paradise, there is a tree under whose shade a rider can travel for a hundred years and still not be able to cross it. Abu Hazim said: I narrated this hadith to Nu'man bin Abi Ayyash Zurqi, so he said that Abu Sa'id Khudri (may Allah be pleased with him) narrated to me that the Messenger of Allah (peace and blessings be upon him) said: In Paradise, there is a tree under which a rider of a fine, well-prepared, swift horse can travel for a hundred years and still not be able to cover it completely.
