Dear scholars, as-salamu `alaykum. What is the Islamic ruling concerning cheating in exams? I graduated from secondary school with excellent marks. However, I cheated in four exams; our teachers gave us the answer to some questions. Now I am in the third year of the faculty of pharmacy. Is it haram (prohibited) for me to study in this faculty? Should I leave it? Once I graduate from the faculty of pharmacy, would my salary be haram due to the fact that I did not deserve to join it in the first place? Jazakum Allah khayran.

As a Muslim minority, can we join non-Muslim political parties and take part in elections?
