Answered by Shaykh Faraz Rabbani
I was told by a Mufti that selling ties is either ‘not desirable’ because it ‘has not been adopted by the learned and god-fearing,’ or ‘totally Haram’ if its origins are from ‘Christian religious dress, as argued by some.’ Is this true? Does this apply to selling other types of clothing, too?
It is permitted to wear ties, and to sell them, without this being disliked.
The fuqaha have talked about this extensively. The conclusion is that it is permitted to wear ties, though better not to when reasonably possible.
It is not considered imitation of non-Muslim because it is not something that is uniquely characteristic of them, unless one does so because one wants to be or look like non-Muslims do. Imitating non-Muslims in actions, dress, or habits is impermissible if it is something that is uniquely characteristic of them, such that if someone saw you in that situation, they would unequivocally think you are a non-Muslim. It is also impermissible, if one wants to be like non-Muslims, such as if one thinks that their ways are superior… [Nahlawi, Durar al-Mubaha]
The argument that the origins of ties are the Christian cross are have not sound basis, as studies of the origins of ties and cravats show. [Shaykh Taqi Usmani and other scholars confirm this ruling.]
If ties are from real silk (=that which is produced from the thread of silkworms), then they are not permitted to be worn or sold. While the Hanafi school permits a certain amount of silk in clothes, this is only if it is not entirely or overwhelming made fro m s ilk, such as silk piping or embroidery. Entire items, such as silk ties, are not permitted. [Naf` al-Mufti wa’l Sa’il of Imam Abdal-Hayy al-Lakhnawi]
