منهم مثل موسى و عيسى ع هل يجوز مع وفور عقلهما و كمال علمهما...
I said, of course this was the case. Imam -asws said: Look, Prophet Musa -as , who has (the title of) Friend of Allah -azwj , when he -as selected seventy pious people (from his -as nation) for the ‘al-Miqad’, surely, he -as had not an element of doubt in their Eman and sincerity, but all of them turned out to be hypocrites.
That is why Allah -azwj Says: And Musa chose out of his people seventy men for Our appointment (7:155) but these hypocrites said instead : we will not believe in you until we see Allah manifestly (2:55), as a result : so the lightning overtook them on account of their injustice.(4:153) So when we see that the selection of those, who were awarded the Prophet-hood by Allah -azwj , turned out to be wrong while they were full of confidence that they have picked up the righteous ones.
Therefore, if a Mursil [64] Prophet -as could not recognise the pious ones with whom he had spent several years, how can a shia in search of a pious guide will ever find one (his Mujtahid)? Thus its on Him -azwj Who is aware of what is hidden in the hearts, to Appoint a Guide -asws /Leader -asws /Imam -asws .
