Tie In Musa عليه السلام Tongue
So it was a lie of Firaun- just an empty statement? I ask because was Musa عليه السلام then able to communicate the word of God in a away that itmam e hujjat be done?
It is just a statement out of animosity. We experience such political statements being made by politicians every day against each other. I am not denying the possibility of coal incident, its just this fact that the above statement is understandable even without any such incident happening in the background.
The message was converted in truth with clarity with the help of his brother Haroon ,perhaps
The message of religion is not very intricate so as to require an eloquent speaker in order to convey it properly. And being a good speaker is not a requirement of prophethood, the only thing all Prophets possess before prophethood is the piety and ethical character of highest levels. Rest of the traits and their personalities vary the same way we see such diversity in other humans. Every Prophet is a great example of piety and ethical character within the bounds of same traits they posses as a human being. Moses (SWS) not being a good speaker does in no way necessitate the message not being converted in truth with clarity. And to get the attention of the monarch of His time, He was given extraordinary miracles which were sufficient to compensate for his lack of speaking skills. In addition to that, Haroon (AS) was given prophethood as well to support him and be his arm in this cause ( as pointed out by sister above ).
