Islam provides clear guidelines on the imitation of non-Muslims, emphasizing the importance of maintaining a distinct Islamic identity. While certain forms of imitation may be permissible, particularly in non-religious matters that do not contradict Islamic teachings, caution is necessary. Muslims are advised to avoid practices that are unique to non-Muslim religions or customs, especially those that may lead to a weakening of Islamic principles.

The clothes of the disbelievers which the Muslims are forbidden to wear are those which are worn exclusively by the disbelievers and are not worn by anyone else. As for those which are worn by both disbelievers and Muslims, there is nothing wrong with wearing them and that is not disliked because they are not exclusive to the disbelievers.

It is not permissible for the Muslim to join the non-Muslims in their festivals and to express joy and happiness on these occasions, or to take the day off work, whether the occasion is religious or secular.

It is not permissible to join in the non-Muslim festivals because this entails imitating or resembling them and taking part in their festivals is a kind of befriending them and showing love for them.

Muslims do not celebrate birthdays because it is a kind of innovation in religion which has no basis in the pure Shari`ah.
