3:140
إِن يَمْسَسْ كُمْ قَرْحٌ فَ قَدْ مَسَّ ٱلْ قَوْمَ قَرْحٌ مِّثْلُ هُۥ وَ تِلْكَ ٱلْ أَيَّامُ نُدَاوِلُ هَا بَيْنَ ٱل نَّاسِ وَ لِ يَعْلَمَ ٱللَّهُ ٱلَّذِينَ ءَامَنُ وا۟ وَ يَتَّخِذَ مِن كُمْ شُهَدَآءَ وَ ٱللَّهُ لَا يُحِبُّ ٱل ظَّٰلِمِينَ
If a wound should touch you - there has already touched the [opposing] people a wound similar to it. And these days [of varying conditions] We alternate among the people so that Allah may make evident those who believe and [may] take to Himself from among you martyrs - and Allah does not like the wrongdoers -
