If it is said: He must inform him through someone other than the apostle that it is in his interest that the apostle is sent to him, so he may know it is his own wrongdoing, our reply will be that on parallel grounds, Allah has informed us through His Messenger and Imams (his forefathers), the Imam’s position and obliged us to obey him; and if we do not know what we should do, it is our own guilt, hence the similarity between two situations.
