Law Of Messengers
Please see : Discussion 31434
The verse of Aal-e-Imran you’re referring to do not describe any principle of itmam-e-hujjah. These verses are more directed toward the Sahaba and are an explanation of this fact that Iman/faith in isolation is not something that should depend on whether prophet lives or die, if one believes in a Prophet then one is ought to show the same level of faith whether or not Prophet lives among them. Therefore, there is no sense in taking it out of context and extract an independent law out of it. There were other verses in Aal-e-imran that describe the whole incident of uhad and the rationale why it all happened i.e. for ‘tamheez’ of Sahab as a part of law of test and trial (ibtila) of Allah.
