Musnad Ahmad 32:283

Yazid narrated to us, he said: Muhammad ibn ‘Amr informed us, he said: Waqid ibn ‘Amr ibn Sa‘d ibn Mu‘adh informed me. Muhammad said: And Waqid was among the most handsome of people, the greatest of them, and the tallest of them. He said: I entered upon Anas ibn Malik, and he said to me: "Who are you?" I said: "I am Waqid ibn ‘Amr ibn Sa‘d ibn Mu‘adh." He said: "You are most like Sa‘d." Then he wept and wept excessively, and said: "May the mercy of Allah be upon Sa‘d; he was among the greatest of people and the tallest of them." Then he said: The Messenger of Allah, peace and blessings of Allah be upon him, sent an army to Ukaydir of Dumah. He sent to the Messenger of Allah, peace and blessings of Allah be upon him, a cloak of silk woven with gold. The Messenger of Allah, peace and blessings of Allah be upon him, wore it, then stood upon the pulpit—or sat—and did not speak. Then he descended, and the people began to touch the cloak and look at it. The Messenger of Allah, peace and blessings of Allah be upon him, said: "Are you amazed by it?" They said: "We have never seen a garment more beautiful than it." The Prophet, peace and blessings of Allah be upon him, said: "The handkerchiefs of Sa‘d ibn Mu‘adh in Paradise are more beautiful than what you see."
