Silsilat al-Ahadith al-Sahihah

Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) narrates that he was breaking a miswak from a miswak tree. He had thin shins, and due to the wind, his garment was lifted from his legs, so the people laughed. The Messenger of Allah (peace and blessings of Allah be upon him) asked, "What are you laughing at?" They said, "O Messenger of Allah! At the thinness of his shins." He (peace and blessings of Allah be upon him) said, "By Him in Whose hand is my soul! In the scale, they will be heavier than Mount Uhud." This hadith is narrated from Sayyiduna Abdullah bin Mas'ud and Sayyiduna Ali bin Abi Talib (may Allah be pleased with them both).
