Divine protection and guardianship (wilayah)

إِذْ هَمَّت طَّآئِفَتَانِ مِنكُمْ أَن تَفْشَلَا وَٱللَّهُ وَلِيُّهُمَا ۗ وَعَلَى ٱللَّهِ فَلْيَتَوَكَّلِ ٱلْمُؤْمِنُونَ

When two parties among you were about to lose courage, but Allāh was their ally; and upon Allāh the believers should rely.

ذَٰلِكَ بِأَنَّ ٱللَّهَ مَوْلَى ٱلَّذِينَ ءَامَنُوا۟ وَأَنَّ ٱلْكَـٰفِرِينَ لَا مَوْلَىٰ لَهُمْ

That is because Allāh is the protector of those who have believed and because the disbelievers have no protector.
