﴿ أَوَلَمَّآ أَصَٰبَتْكُم مُّصِيبَةٌۭ قَدْ أَصَبْتُم مِّثْلَيْهَا قُلْتُمْ أَنَّىٰ هَٰذَا ۖ قُلْ هُوَ مِنْ عِندِ أَنفُسِكُمْ ۗ إِنَّ ٱللَّهَ عَلَىٰ كُلِّ شَىْءٍۢ قَدِيرٌۭ ﴾

“AND DO YOU, now that a calamity has befallen you after you had inflicted twice as much [on your foes], ask yourselves, "How has this come about?" Say: "It has come from your own selves." Verily, God has the power to will anything:”

He then mentioned their misfortune on the Day of Uhud, saying: (And was it so, when a disaster smote you) on the Day of Uhud, (though you had smitten (them with a disaster) twice (as great)) as you inflicted on the people of Mecca, on the Day of Badr, a disaster twice that inflicted on you on the Day of Uhud, (that ye said: How is this?) how can this befall us when we are Muslims. (Say) O Muhammad: (It is from yourselves) it is due to the transgression you committed yourselves when you left your positions. (Lo! Allah is Able to do all things) whether it is punishment or something else.
