Answered by Shaykh Faraz Rabbani
Question: Would it be considered ‘imitating the unbelievers’ to wear denim clothing or a sari?
Answer: In the name of Allah, Most Merciful.
Walaikum assalam wa rahmatullahi wa barakatuh,
It is not disliked to wear denim clothing (such as a jilbab for women, or loose jeans), if it fulfills the conditions and proprieties of modest Muslim clothing.
As for a sari, if it is properly covering, loose, and modest, then it is permitted to wear without dislike. The sari is a common cultural dress of Muslims and is not a distinguishing sign of disbelief or corruption.
This is what the texts of the Hanafi school would entail, and what leading scholars we have consulted state.
And Allah alone gives success.
