﴿ إِذْ يَقُولُ ٱلْمُنَٰفِقُونَ وَٱلَّذِينَ فِى قُلُوبِهِم مَّرَضٌ غَرَّ هَٰٓؤُلَآءِ دِينُهُمْ ۗ وَمَن يَتَوَكَّلْ عَلَى ٱللَّهِ فَإِنَّ ٱللَّهَ عَزِيزٌ حَكِيمٌۭ ﴾

“At the same time, the hypocrites and those in whose hearts was disease were saying, "Their faith has deluded these [believers]!" But he who places his trust in God [knows that], verily, God is almighty, wise.”

When the hypocrites and those in whose hearts is a sickness a weakness of faith said ‘Their religion has deluded them’ that is the Muslims for they had set out to fight a large army despite their small number in the mistaken belief that they will be victorious because of this. God exalted be He says in response to them but whoever relies on God whoever puts his trust in Him he will triumph; for truly God is Mighty His way will prevail Wise in His actions.
