Although Qur'an is not direct on justice for non-Muslims but on three occasions this book clearly enunciates that the good deeds of the humans belonging to other religious backgrounds are not to be wasted before Allah.,[3][4] and[5] from these verses, it can be inferred directly that Creator i.e. Allah has nothing to do with religious background but the good deeds of the actor will always be rewarded both in this world and hereafter too, enshrining the justice for all by Allah.
These verses appear to state that as long as there is a belief in God, the Day of Judgment and that they remain righteous, justice shall be done and these people shall find their reward in jannah.
[23] Another Qur’anic interpretation that supports this claim is seen when Glassé argues that “in theory, Islam accepts Christianity as a divinely revealed religion”.
[24] This is based on verses in the Qur’an which state that the Believers are not solely Muslims, and that these people will be justly rewarded for their prayers and way of life with a place in jannah.
[25] Alternatively, the Qur’an also offers many verses which seem to demonstrate that the only form of justice for all non-Muslims is one where they are all condemned to jahannam due to their failure to follow Muhammad as a prophet of God.
This would be in conjunction with other interpretations of aforementioned Qur’anic verses that promulgate the view that divine justice regarding non-Muslims is based on their deeds and intentions if they still practice monotheism.
[29] However, in the same verse, the Qur’an also proposes to “forgive them, and overlook their misdeeds: for God loveth those who are kind.”[30] The Qur’an contains a double message with regard to justice for non-Muslims; it appears to both proclaim that the divine justice in the afterlife for People of the Book will be their place in jannah (presuming they have lived righteously), whilst simultaneously stating that these very people deserve a place in jahannam for their beliefs, no matter how righteous they may live.
The Qur’an also contains verses that command Muslims to fight against non-Muslims,[31][32][33] whilst concurrently declaring that people who practice monotheism and live righteously will have nothing to fear in the afterlife as divine justice shall reward them with a place in jannah.
