The principle of Divine grace, the idea of believers` non entrance into the Hell and the reason why of creating the Garden and the Hell for people of happiness and people of sin respectively, have put the verse 71 of Maryam among difficult verses. Commentators have sought very much to oppose any idea of disagreement with regard to other verses and reasons and in this way various views have been presented. Lack of a publicly accepted conclusion is a sign for not the problem not to be solved. Three approaches may be found in the commentary of the verse: in one the entrance has been taken to mean entering into, in another to mean dominance and the third is an ethical usage. Contrary to the most commentators, Allameh Tabtaba`I has paid a special attention to the problem. The paper, studying comprehensively and critically different commentaries, has viewed Allameh`s solution as the right one.
