The permission of husband has been always an important subject among the Islamic jurists. The principle of necessity of wife's permission for exit from the house has been accepted by the jurists based on traditions. The main question on this subject is about the boundaries of permission. So many Imami jurists (senior and recent) such as Sheikh Mofid, Sheikh Toosi, Abossalah Halabi, Allama Helli, Imam Khomayni and Ayatollah Sistani have explained the necessity of unconditional permission and some contemporaneous jurists such as Ayatollah Khoyi, Sheikh Mohammad Mahdi Shamsoddin, Sayyed Mohammad Hosayn Fazlollah, Ayatollah Mohammad Mousavi Bojnordi and Ayatollah Jannati have explained the necessity of conditional permission. Some of the Quranic verses refer to the principle of wife's permission indirectly, but we did not find any frank verse about the permission; so we will study some traditions on this subject from A'emma.
