Musnad Ahmad 27:1263

Zakariya ibn 'Adi narrated to us, 'Ubayd Allah ibn 'Amr informed us, from 'Abd Allah ibn Muhammad ibn 'Aqil, from Ibn 'Umar, who said: The Messenger of Allah (may Allah bless him and grant him peace) clothed me in a garment from the garments of *sayra'* (silk) which Fayruz had gifted to him. I put on the lower garment (*izar*), and it overwhelmed me in length and width, so I dragged it. Then I put on the upper garment (*rida'*) and covered my head with it. The Messenger of Allah (may Allah bless him and grant him peace) took hold of my shoulder and said: "O 'Abd Allah ibn 'Umar, raise your lower garment, for whatever of the lower garment touches the ground below the ankles is in the Fire." 'Abd Allah ibn Muhammad said: I never saw a person more diligent in tucking up his garment than 'Abd Allah ibn 'Umar.
