Salvation of Followers of Religions other then Islam and Divine Justice from Ayatollah Motahhari's Point of View

Although discussed only by theologians in the past, the topic of the acceptance of non-Muslims’ good deeds and their salvation and redemption has entered the public arena as an issue of divine justice at the present time due to the expansion of information technology which has facilitated communication among followers of different religions. Thequestion raised is whether the good deeds done by non-Muslims or by polytheists have any rewards in the hereafter or the path to salvation and redemption is exclusive to belief in Islam and following its path. Is it possible to achieve salvation and redemption through belief in other religions along with good deeds? Otherwise, how is this compatible withdivine justice? With regard to the fact that this issue was introduced in a serious way at Ayatollah Motahhari’s time, he, as a sagacious Islamic scholar and a vigilant observer and as someone familiar with the requirements of the time and place, dealt with the issue of salvation of the followers of other religions from an Islamic perspective discussing itsrelationship with divine justice.
