Abu Dawud Book 27, Hadith Number 4041.
Chapter : The view that disapproves of wearing silk.
Narated By ‘Aisha, Ummul Mu’minin : The Apostle of Allah (PBUH) once prayed wearing a garment having marks. He looked at its marks. When he saluted, he said: Take this garment of mine to Abu Jahm, for it turned my attention just now in my prayer, and bring a simple garment without marks.
