← Previous Hadith The Messenger of Allah granted a concession to 'Abdur-Rahman bin 'Awf and Az-Zubair bin Al-'Awwam allowing them to wear silken shirts because of scabies that they were suffering from.

Sunan an-Nasa'i Book 48, Hadith 271 Next Hadith → "We were with 'Utbah bin Farqad when the letter of 'Umar came, saying that the Messenger of Allah said: 'No one wears silk except one who has no share of it in the Hereafter, except this much.'" And Abu 'Uthman gestured with the two fingers that are next to the thumb. And I saw the two of them pointing to the borders of the Tayalisah, so that I could see the Tayalisah.
