"With regard to the phrase “imitation of the kuffaar”, that does not mean that we should not use anything that they have manufactured. No one says such a thing. At the time of the Prophet (peace and blessings of Allaah be upon him) and afterwards the people used to wear clothes made by the kuffaar and use vessels made by them. 

Imitation of the kuffaar means imitating their clothing and appearance, and the customs that are unique to them. It does not mean that we should not ride what they ride or wear what they wear. But if they ride in a specific way that is unique to them, then we should not ride in that way. If they tailor their clothes in a certain fashion that is unique to them, we should not do likewise. But if we have cars that are similar to theirs and fabric that is similar to theirs, there is nothing wrong with that."
