Friends joking and calling one another by Jewish or Christian names

A: This act is not permissible as it entails imitating non-Muslims by using their names. The Prophet (peace be upon him) said, He who copies any people is one of them. You are obliged to avoid using these foreign names, even if you joke, when calling one another.May Allah grant us success. May peace and blessings of Allah be upon our Prophet Muhammad, his family and Companions!
