That granting of victory to the believers and the vanquishing of the disbelievers is because God is Patron Ally and Helper of those who believe and because the disbelievers have no patron.
- 47:1111
ذَٰلِكَ بِأَنَّ اللَّهَ مَوْلَى الَّذِينَ آمَنُوا وَأَنَّ الْكَافِرِينَ لَا مَوْلَىٰ لَهُمْ
That is because God is the Protector of the believers, and that the unbelievers have no protector.
