It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Holy Prophet (peace and blessings be upon him) said: In Paradise, there is a tree such that if a rider were to travel in its shade for a hundred years, he would still not be able to cross it. If you wish, recite this verse: "They will be in extended and long shades." And for the coolness of their eyes, what things have been concealed.
