Ash-Shaykh Saalih al-Fawzan, may Allah preserve him, said when asked about the ruling on wearing ties:

..والسؤال الثالث في الكرافته على ما يبدو لي.هذه تُضاهي تعليق النصارى الصُّلب على أعناقهم

“Pertaining to the third question concerning the ruling on ties, what is apparent to me is that this resembles what the Christians tie on their neck of the cross”
. فيه مشابهة .
لأن النصارى يُعلّقون الصليب على أعناقهم فقلّدهم بعض المسلمين و جعل هذه الكرافته. هذا تشبه

“In it is a form of imitation because the Christians tie the cross around their neck, whereas some of the Muslims have begun to blind-follow them in making these ties, (and thus) this is a form of imitation.”

وليست هذه من ملابس المسلمين ، إنما هي سارية إلى.إلينا من مجتمع الكفار وهم الأصل
الأصل فيها أنها تعليق الصليب فلا يجوز أن يلبس المسلم هذه الكرافته.

“And it is not from the clothing of the Muslims. Rather, it was merely imported to us from the places of the kufaar, while they are the originators of it. The origin concerning it was to tie the cross. Therefore, it is not permissible for the Muslim to wear such ties.”

وإذا كام صاحب العمل يُجبره عليها فالأعمال كثيرة والحمد لله . ينتقل إلى دائرة أخرى أو إلى عمل آخر ).

“And if his boss at work obliges him to wear it, then there are plenty other places to work walhamdulilah. He goes to another section or to another job.”

Likewise Ash-Shaykh Abdul Muhsin al-Abbaad, may Allah preserve him, said:

لا . هذه لا يجوز استعمالها . لأن هذه من لباس الكفار و مخالفتهم مطلوبة .

“No, this is not permissible to use, because this is from the clothing of the kufaar and being different from them is requested (in the religion).”

وحتى في اللباس الذي هو البناطيل . يعني التي تصف الأحجام ، هذه إذا كان الإنسان يحتاج إليها فإنه يوسعها ، بحيث تكون واسعة ، حتى يكون مخالف للكفار وغير مشابه للكفار )

“Even for the clothing of tight trousers of which shows the shape of the body, (regarding this) if a person is in need of it, then let him expand its size so that it may become wide in order that he be different from the kufaar, and so that he doesn’t imitate them”
