Musnad Abu Ya'la al-Mawsili 115:271

Zuhayr narrated to us, Yunus ibn Muhammad narrated to us, Shayban narrated to us, from Qatadah, from Anas, that a jubbah (outer garment) made of silk brocade was gifted to the Messenger of Allah, may Allah bless him and grant him peace, and he used to forbid silk. The people were amazed by it, so he said, "By the One in Whose hand is my soul, the handkerchiefs of Sa'd ibn Mu'adh in Paradise are better than this."
