Musnad Ahmad 32:1511

'Abd al-Wahhab narrated to us, from Sa'id, from Qatadah, from Anas ibn Malik, that Ukaydir of Dumah gifted the Messenger of Allah, may Allah bless him and grant him peace, a silk jubbah (outer garment). That was before the Prophet of Allah, may Allah bless him and grant him peace, forbade silk. He wore it, and the people were amazed by it. The Prophet, may Allah bless him and grant him peace, said: "By the One in Whose hand is the soul of Muhammad, the handkerchiefs of Sa'd in Paradise are better than this."
