Majma al-Zawaid 14492 — The description of Uthman

Abdullah bin Shaddad bin al-Had narrates: On a Friday I saw Sayyiduna Uthman al-Ghani (may Allah be pleased with him) on the pulpit. He was wearing a coarse Adani waist-wrap whose price was four or perhaps five dirhams, and he had a Kufan sheet dyed with red clay. He was lightly built, his beard was long and his face was handsome.
Al-Tabarani recorded it, and its chain is hasan (good).
