"Narrated Al-Muttalib: When Uthman ibn Maz'un died, he was brought out on his bier and buried. The Prophet (peace be upon him) ordered a man to bring him a stone, but he was unable to carry it. The Apostle of Allah (peace be upon him) got up and going over to it rolled up his sleeves. The narrator Kathir told that al-Muttalib remarked: The one who told me about the Apostle of Allah (peace be upon him) said: I still seem to see the whiteness of the forearms of the Apostle of Allah (peace be upon him) when he rolled up his sleeves. He then carried it and placed it at his head saying: I am marking my brother's grave with it, and I shall bury beside him those of my family who die."
