Qur'an 3:140
إِن يَمْسَسْكُمْ قَرْحٌ فَقَدْ مَسَّ ٱلْقَوْمَ قَرْحٌ مِّثْلُهُۥ ۚ وَتِلْكَ ٱلْأَيَّامُ نُدَاوِلُهَا بَيْنَ ٱلنَّاسِ وَلِيَعْلَمَ ٱللَّهُ ٱلَّذِينَ ءَامَنُوا۟ وَيَتَّخِذَ مِنكُمْ شُهَدَآءَ ۗ وَٱللَّهُ لَا يُحِبُّ ٱلظَّـٰلِمِينَ
“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 Allāh may make evident those who believe and [may] take to Himself from among you martyrs - and Allāh does not like the wrongdoers -”
