Answered by Shaykh Faraz Rabbani
Question: Nowadays, there are many clothes being sold that are made of Endi Silk. Is it haram for men to wear clothes made from this material?
Answer: Walaikum assalam wa rahmatullahi wa barakatuh,
I pray this finds you in the best of health and spirits. Natural silk (from silkworms) is impermissible to wear for men–though permitted for women. It would appear that Endi (or: Eri) silk [http://en.wikipedia.org/wiki/Eri_silk] is such a silk, and therefore the mentioned ruling would apply.
