It was narrated from `Umar bin al-Khattab that he said: Wear izars and rida`s and wear shoes, but take off boots and pants; throw away the stirrups and jump onto your mounts. You should wear rough clothes and practise archery, and keep away from luxury and the dress of the non-Arabs, Beware of silk, for the Messenger of Allah (ﷺ) forbade it and said: `Do not wear silk except this much` - and the Messenger of Allah (ﷺ) gestured with two fingers.
