﴿ أَفِى قُلُوبِهِم مَّرَضٌ أَمِ ٱرْتَابُوٓا۟ أَمْ يَخَافُونَ أَن يَحِيفَ ٱللَّهُ عَلَيْهِمْ وَرَسُولُهُۥ ۚ بَلْ أُو۟لَٰٓئِكَ هُمُ ٱلظَّٰلِمُونَ ﴾

“Is there disease in their hearts? Or have they begun to doubt [that this is a divine writ]? Or do they fear that God and His Apostle might deal unjustly with them? Nay, it is [but] they, they who are doing wrong [to themselves]!”

Is there a sickness disbelief in their hearts? Or are they in doubt are they uncertain of his prophethood or do they fear that God and His Messenger will be unjust to them? in judgement in other words that they will be wronged therein? No! Rather those they are the wrongdoers for shunning him.
