Narrated Abu `Uthman: While we were with `Utba. `Umar wrote to us: The Prophet said, "There is none who wears silk in this world except that he will wear nothing of it in the Hereafter." ' Abu `Uthman pointed out with his middle and index fingers. This hadith has also been narrated by Abu `Uthman.

‘Hassan bin Umar narrated to us, he said: Muammar narrated to us, he said: Our father narrated to us, Abu Uthman narrated to us’ and Abu Uthman gestured with his two fingers, the index and the middle finger.
