One of the main issues that engaged the mind of religious persons is the command of religion about shave. The issue of shaving among Shiite jurists was first introduced at the end of seventh century but specifying its legality was started in the tenth or eleventh century in shiite’s jurisprudence books.According to the different reasons, Quran, traditions, consencus, fame, wisdom and etc, the believers in shave legality deduced some documents, but by reviewing them exactly it can be found that none of them has enough competence to prove shave legality.On the other hand, from the early to now, none of our prophets, jurists and Islamic law scientists has not shaved their beard. So based on the precaution condition it should not be shaved.
