Punishment for slandering the Prophet is death in Islam

Re: Punishment for slandering the Prophet is death in Islam

You have answered this question yourself below. Apparently its not allowed to ‘‘guess’’ the ruling of a matter in Islam even if the person guesses correctly! A persons judgement must be grounded in knowledge of the Quran and Sunnah of the Messenger SallAllaahu alaihi wa alihi wa Sallam in order to do ijtihad (make a ruling).
Although the companions (may Allaah be pleased with him) were able to do this, we in our times are not. Hence the importance of knowledgeable ulema/courts especially when the judgement of individuals is not reliable
