فَتَرَى ٱلَّذِينَ فِى قُلُوبِهِم مَّرَضٌۭ يُسَٰرِعُونَ فِيهِمْ يَقُولُونَ نَخْشَىٰٓ أَن تُصِيبَنَا دَآئِرَةٌۭ ۚ فَعَسَى ٱللَّهُ أَن يَأْتِىَ بِٱلْفَتْحِ أَوْ أَمْرٍۢ مِّنْ عِندِهِۦ فَيُصْبِحُوا۟ عَلَىٰ مَآ أَسَرُّوا۟ فِىٓ أَنفُسِهِمْ نَٰدِمِينَ
And thou seest those in whose heart is a disease race toward them, saying: We fear lest a change of fortune befall us. And it may happen that Allah will vouchsafe (unto thee) the victory, or a commandment from His presence. Then will they repent them of their secret thoughts.
