Monotheism and exclusive reliance on Allah (Tawhid)

إِنَّهُمْ لَن يُغْنُوا۟ عَنكَ مِنَ ٱللَّهِ شَيْـًٔا ۚ وَإِنَّ ٱلظَّـٰلِمِينَ بَعْضُهُمْ أَوْلِيَآءُ بَعْضٍ ۖ وَٱللَّهُ وَلِىُّ ٱلْمُتَّقِينَ

Indeed, they will never avail you against Allāh at all. And indeed, the wrongdoers are allies of one another; but Allāh is the protector of the righteous.
