What should a student do regarding a Jewish university professor who might mock the Prophet (peace be upon him) or Islam, taking into account the student's lack of eloquence and quick temper? And how can one respond to such people?

May Allah reward your zeal and diligence in defending your religion. When a Muslim hears falsehood concerning the Sharia of Allah and the exalted status of prophethood, it is incumbent upon him to clarify the truth and refute falsehood. This requires knowledge and wisdom. Therefore, continue on the path of seeking knowledge, which will enable you to clarify the truth, and adorn yourself with good character and wisdom in dealing with those who differ, for this is the most upright path for inviting to the religion of Allah.
