This video is a scientific study aiming to answer whether all the many Muslims present at Ghadeer Khumm heard Prophet Muhammad's (PBUH) important sermon directly and with their own ears. If so, what excuse remains for them in not implementing the divine command of God and the order of the Prophet? This video provides the simulation of the Prophet's voice wave propagation at the exact location of his pulpit during the sermon of Ghadeer Khumm to address this question.
