(Ali-Imran) 3 : 140
إِنْ يَمْسَسْكُمْ قَرْحٌ فَقَدْ مَسَّ الْقَوْمَ قَرْحٌ مِثْلُهُ ۚ وَتِلْكَ الْأَيَّامُ نُدَاوِلُهَا بَيْنَ النَّاسِ وَلِيَعْلَمَ اللَّهُ الَّذِينَ آمَنُوا وَيَتَّخِذَ مِنْكُمْ شُهَدَاءَ ۗ وَاللَّهُ لَا يُحِبُّ الظَّالِمِينَ
If a wound is affected you, the other people also had been affected with similar wounds, We are alternating these days of varying success and failure among mankind so that Lord Allah to Know those who believed and to choose martyrs from among you, and Allah doesn’t love the wrongdoers.
