إِن يَمسَسكُم قَرحٌ فَقَد مَسَّ القَومَ قَرحٌ مِثلُهُ ۚ وَتِلكَ الأَيّامُ نُداوِلُها بَينَ النّاسِ وَلِيَعلَمَ اللَّهُ الَّذينَ آمَنوا وَيَتَّخِذَ مِنكُم شُهَداءَ ۗ وَاللَّهُ لا يُحِبُّ الظّالِمينَ

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 -
