برهان حفظ شریعت و وجود امام عصر (عج)

islamic shariyat is the last divine shariyat and is obligatory for all responsible person (mokallaf) until the day of judgment to know and practice it. based on this, saving the shariyat in complete, in all times is obligatory. so the other responsible people can be able to achieve it. except the infallible imama.s., there is not any other choice to protect the shariyat completely; therefore, the existence of an imam for all times is necessary. the examples for infallible imamsa.s. after the prophetp.b.u.h. are the shiia imams (the twelve imamsa.s.) that the twelfth of them is his excellency imam mahdim.a.h.h.a. with believing in his excellency’s existence in the time of occultation, we can be sure that the reasoning for shariyat given by the prophetp.b.u.h and the imams of the householda.s. in their presence time are still saved. based on this the shiia scholars are not in need of any authentic and necessary resources for deducing the regulations and therefore will not need to deduce based on logical deduction by analogy and justice preference and other doubtful, not authentic resources that are used in sunni jurisprudence
