It is narrated from Sayyiduna Ali (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him and his family) instructed Sayyiduna Ibn Mas’ud (may Allah be pleased with him) to climb a tree and bring something down from it. He climbed the tree, and when the noble Companions saw his thin, weak shins as he was climbing, they began to laugh. But the Messenger of Allah (peace and blessings be upon him and his family) said: Why are you laughing? On the Day of Resurrection, Abdullah’s legs will be heavier on the scale than Mount Uhud.
