وَمَن لَّا يُجِبْ دَاعِىَ ٱللَّهِ فَلَيْسَ بِمُعْجِزٍۢ فِى ٱلْأَرْضِ وَلَيْسَ لَهُۥ مِن دُونِهِۦٓ أَوْلِيَآءُ ۚ أُو۟لَٰٓئِكَ فِى ضَلَٰلٍۢ مُّبِينٍ
And whoso respondeth not to Allah's summoner he can nowise escape in the earth, and he hath no protecting friends instead of Him. Such are in error manifest.
