On Resurrection Day all disagreement among people will end. The Koranic verses represent this view:
1. We settled the children of Israel in a respectable dwelling and provided then with wholesome things. They did not disagree until knowledge came to them. Your Lord will decide among them on Resurrection Day concerning whatever they have been disagreeing about. (10:93)
2. God will judge between you on Resurrection Day concerning what you (all) have been disagreeing about. (22:69)
3. We gave them explanations about the Matter. They only disagreed after knowledge had come to them, out of envy towards one another your Lord will judge among them on Resurrection Day concerning anything they may have been differing over. (45:17)
4. We have merely sent the Book down to you may explain to them what they are differing over, and as a guidance and mercy for folk who believe. (16:64)
