Differences in the views on Qiyamat
The Bahai belief about Qiyamat - The Day of Judgement, comprises of three elements. Of these, one is that the previous prophets announced the signs for the advent of their successors, albeit in an ambiguous and unclear manner. The religious scholars interpreted these signs in their own ways and explained them downwards to their followers as per the literal meaning of these signs. The Bahais assert that, as in the past, the Holy Quran has explained the signs for the advent of the Bab and Bahaullah. The collective term for these signs is "Qiyamat". The Islamic scholars interpreted these signs literally and became the cause for misguiding the entire Muslim community. It is due to this that Muslims have rejected Bab and Bahaullah.
