Abu Dawud Book 27, Hadith Number 4028.
Chapter : Wearing clothes made of silk and wool khazz.
Narated By Abu Amir or Abu Malik : Abdur Rahman ibn Ghanam al-Ash’ari said: Abu Amir or Abu Malik told me–I swear by Allah another oath that he did not believe me that he heard the Apostle of Allah (PBUH) say: There will be among my community people who will make lawful (the use of) khazz and silk. Some of them will be transformed into apes and swine.
Abu Dawud said: Twenty Companions of the Apostle of Allah (may peace be upon him) or more put on khazz. Anas and al-Bara’ b. ‘Azib were among them.
