﴿ وَمَا لَكُمْ لَا تُؤْمِنُونَ بِٱللَّهِ ۙ وَٱلرَّسُولُ يَدْعُوكُمْ لِتُؤْمِنُوا۟ بِرَبِّكُمْ وَقَدْ أَخَذَ مِيثَٰقَكُمْ إِن كُنتُم مُّؤْمِنِينَ ﴾

“And why should you not believe in God, seeing that the Apostle calls you to believe in [Him who is] your Sustainer, and [seeing that] He has taken a pledge from you? [Why should you not believe in Him] if you are able to believe [in anything]?”

When the call of Islam is given, it is based on clear reasoning in its preliminary stages. The second stage is marked by victory in its immediate surroundings. In the first stage, only those who have the capacity to see the inherent greatness of a thing solely on the level of reasoning are courageous enough to make sacrifices for Islam. But when Islam has already been crowned by success, every individual is able to see its greatness and everybody feels proud of coming forward and offering his life and property for its sake. One who spends for the cause of Islam in the early stages has to do it without thought of reward, while in the latter stage, whatever a man spends is redoubled in this world itself, as a reward in various forms. That explains why, in the eyes of God, each group has a different status.
