Majma al-Zawaid 14591 — The physical description of Ali

Al-Waqidi narrates: It is said that Sayyiduna Ali bin Abi Talib (may Allah be pleased with him) was a wheat-complexioned man of medium height, and he was heavily built. His shoulders were broad, his beard was long, there was no hair on the front of his head, his belly was large, his eyes were big, and the hair of his head and beard was white.
Al-Tabarani recorded it, and its narrators up to al-Waqidi are thiqat (trustworthy).
