Surah Aali Imran (The Family of Imran), Verse 165

اَوَلَمَّاۤ اَصَابَتْكُمْ مُّصِیْبَةٌ قَدْ اَصَبْتُمْ مِّثْلَیْهَا قُلْتُمْ اَنّٰی هٰذَا قُلْ هُوَ مِنْ عِنْدِ اَنْفُسِكُمْ اِنَّ اللّٰهَ عَلٰی كُلِّ شَیْءٍ قَدِیْرٌ ۟

Awa lammaaa asaabatkum museebatun qad asabtum mislaihaa qultum annaa haazaa qul huwa min 'indi anfusikum; innal laaha 'alaa kulli shai'in Qadeer

“What! When a single disaster smites you, although ye smote (your enemies) with one twice as great, do ye say?- "Whence is this?" Say (to them): "It is from yourselves: For Allah hath power over all things."”
