imranshaykh said:The belief in the 12th Imam is an Islamic concept. So how can the Babi and the Bahai sources supercede the Islamic sources in this regard.
As has been repeatedly said, we do not. Other than by memorization, how would you know it if it was in your hands? How were the Jews to see the truth of Jesus? How were the arabs to know the words of Muhammd were in fact God's words, not his own?
Now apply that standard to the Babi and Baha'i Scriptures. God doeth what He wills, and no man shall be asked permission.
