Sura al-Māʾidah 5:52

فَتَرَى ٱلَّذِينَ فِى قُلُوبِهِم مَّرَضٌ يُسَٰرِعُونَ فِيهِمْ يَقُولُونَ نَخْشَىٰٓ أَن تُصِيبَنَا دَآئِرَةٌ فَعَسَى ٱللَّـهُ أَن يَأْتِىَ بِٱلْفَتْحِ أَوْ أَمْرٍ مِّنْ عِندِهِۦ فَيُصْبِحُوا۟ عَلَىٰ مَآ أَسَرُّوا۟ فِىٓ أَنفُسِهِمْ نَٰدِمِينَ

fatarā lladhīna fī qulūbihim maraḍun yusāriʿūna fīhim yaqūlūna nakhsha an tuṣībanā dāʾiratun fa-ʿaṣā allāhu an yaʾtiya bil-fatḥi aw amrin min ʿindihi fa-yuṣbiḥū ʿalā mā asarrū fī anfusihim nādimīna

Those in whose hearts is a disease - thou seest how eagerly they run about amongst them, saying: "We do fear lest a change of fortune bring us disaster." Ah! perhaps Allah will give (thee) victory, or a decision according to His will. Then will they repent of the thoughts which they secretly harboured in their hearts.
