What is the ruling on wearing sports clothes in which there are symbols belonging to the kuffar, such as sports jerseys on which there are symbols of Italy or Germany or America, or on which are written the names of some of the kaafir players.
Clothing on which there are symbols of the kuffaar is subject to further discussion, as follows:
1. If these symbols represent the religion of the kuffaar such as crosses and the like, in this case it is not permissible to import these clothes or to sell them or to wear them.
2. If these symbols represent veneration of anyone among the kuffaar, by putting his picture or writing his name and so on, they are also haraam as stated above.
3. If these slogans do not have to do with worship or veneration of any person, rather they are permissible trademarks, then there is nothing wrong with them.
And Allaah is the source of strength. May Allaah send blessings and peace upon our Prophet Muhammad and his family and Companions.
