Sayyiduna Ali (may Allah be pleased with him) narrates that once the Prophet (peace and blessings be upon him) ordered Sayyiduna Ibn Mas’ud (may Allah be pleased with him), so he climbed a tree. The Prophet (peace and blessings be upon him) had instructed him to bring something. When the noble Companions (may Allah be pleased with them) saw Sayyiduna Abdullah bin Mas’ud (may Allah be pleased with him) climbing the tree, their gaze fell upon his shins. Seeing his thin shins, they began to laugh. The Prophet (peace and blessings be upon him) said:“Why are you laughing? Indeed, Abdullah’s one leg will be heavier on the scale of deeds on the Day of Resurrection than the mountain of Uhud.”
