إِن يَمْسَسْكُمْ قَرْحٌۭ فَقَدْ مَسَّ ٱلْقَوْمَ قَرْحٌۭ مِّثْلُهُۥ ۚ وَتِلْكَ ٱلْأَيَّامُ نُدَاوِلُهَا بَيْنَ ٱلنَّاسِ وَلِيَعْلَمَ ٱللَّهُ ٱلَّذِينَ ءَامَنُوا۟ وَيَتَّخِذَ مِنكُمْ شُهَدَآءَ ۗ وَٱللَّهُ لَا يُحِبُّ ٱلظَّٰلِمِينَ
If ye have received a blow, the (disbelieving) people have received a blow the like thereof. These are (only) the vicissitudes which We cause to follow one another for mankind, to the end that Allah may know those who believe and may choose witnesses from among you; and Allah loveth not wrong-doers.
Surah Aal-i-Imraan(3:140)
