7. A number of our people have narrated from Sahl ibn Ziyad from Muhammad ibn ‘Isa from Safwan from Yusuf ibn Ibrahim who has said the following: “I once visited abu ‘Abd Allah , and I was wearing a Jubbah of silk and al-Taylisan (pallium) of silk. He (the Imam) looked at me and I asked saying, ‘I pray to Allah to keep my soul in service for your cause, I am wearing a Taylisan of silk and a Jubbah of silk, what do you say about them?’ He (the Imam) said, ‘Silk is not unlawful.’ I then said, ‘Its warp is abrisam (silk from silk worm as opposed to that from certain plant fibers or synthetic). He (the Imam) said, ‘Abrisam is not unlawful because when al-Husayn , was murdered, he was wearing abrisam and jubbah of silk.’ He (the Imam) then said, ‘Abd Allah ibn al-‘ Abbas was sent to al-Khawarij by ’Amir al-Mu’minin and he stood before them wearing the best of his dresses with the best perfumes and with the best stumper. They said, ‘O ibn al- ‘Abbas you are the best of people to us but you have come wearing the dress of the tyrants and riding the stumper of the tyrants.’ He read to them this verse, ‘Say, who has made unlawful the beauties that Allah has brought out for His servants and the best sustenance.’ So dress up and beautify; Allah is beautiful and He loves beauty but it must be of the lawful ones.’”
