Is Belief In Muhammad ﷺ Necessary?
If you take Quranic verse in isolation then you will conclude that there is no need to believe in Prophet Mohammad saw. If you read tadaburi quran, Amin Islahi sb has mentioned the reasoning based on quranic verses. Hadith is not independent source of Islam. On this issue, ghamidi sb has little different view than Amin islahi sb. He thinks, if a person is convinced that prophet Mohammad saw is messanger and denies it then he will be punished. However, a person is not convinced then there is no issue. He will be judged accordingly. Itmam hujjat concept existed before ghamidi sb but they way he describe is something different.
