Rajah (literally "return") is a theological concept in some Islamic traditions, particularly within Twelver Shia Islam, referring to the return of certain individuals to life before the final Day of Resurrection. During the time of the Mahdi's appearance, a group of highly righteous believers and utterly wicked disbelievers will be resurrected to witness the establishment of divine justice. The righteous will witness the triumph of truth, while the wicked will suffer the humiliation of witnessing their falsehood exposed.
This concept is based on interpretations of Quranic verses (27:83-87) and Hadith narrations understood by Shia scholars. Mainstream Sunni theology generally understands the "return" only as the Second Coming of Prophet Isa (Jesus). Rajah is distinct from the general resurrection (qiyamah); it is a return for a select group to witness the final victory of justice in this world. This fulfills divine promises and allows believers to experience victory.
Sunni scholars generally interpret the cited verses as referring to the general resurrection. However, belief in the Second Coming of Jesus is common to both. For those who believe in rajah, it reinforces the certainty that justice will ultimately prevail. It serves as a warning to oppressors that they may face their deeds in this world as well. The concept emphasizes divine justice,no good deed goes unrewarded, and no evil goes unpunished.
The believer, regardless of their specific view, trusts in Allah's justice and awaits the ultimate triumph of truth. Differences on eschatological details remind that while core beliefs are shared, some matters are left to scholarly inquiry. The believer focuses on what is certain: the Day of Judgment is coming, and the best preparation is faith and righteous deeds. The details are in Allah's knowledge.
