أُوْلَٰٓئِكَ ٱلَّذِينَ يَعۡلَمُ ٱللَّهُ مَا فِي قُلُوبِهِمۡ فَأَعۡرِضۡ عَنۡهُمۡ وَعِظۡهُمۡ وَقُل لَّهُمۡ فِيٓ أَنفُسِهِمۡ قَوۡلَۢا بَلِيغٗا
English translation: Those (are) the ones who knows Allah what (is) in their hearts so turn away from them and admonish them and say to them concerning their souls a word penetrating
