Full Sharh — Musnad Ahmad 285
حَدَّثَنَا يَزِيدُ، حَدَّثَنَا عَاصِمٌ، عَنْ أَبِي عُثْمَانَ النَّهْدِيِّ، عَنْ عُمَرَ بْنِ الْخَطَّابِ، رَضِيَ اللَّهُ عَنْهُ أَنَّهُ قَالَ اتَّزِرُوا وَارْتَدُوا وَانْتَعِلُوا وَأَلْقُوا الْخِفَافَ وَالسَّرَاوِيلَاتِ وَأَلْقُوا الرُّكُبَ وَانْزُوا نَزْوًا وَعَلَيْكُمْ بِالْمَعَدِّيَّةِ وَارْمُوا الْأَغْرَاضَ وَذَرُوا التَّنَعُّمَ وَزِيَّ الْعَجَمِ وَإِيَّاكُمْ وَالْحَرِيرَ فَإِنَّ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ قَدْ نَهَى عَنْهُ وَقَالَ لَا تَلْبَسُوا مِنْ الْحَرِيرِ إِلَّا مَا كَانَ هَكَذَا وَأَشَارَ رَسُولُ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ بِإِصْبَعَيْهِ.
English Translation
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.
