Surah Aali Imran (The Family of Imran), Verse 140

اِنْ یَّمْسَسْكُمْ قَرْحٌ فَقَدْ مَسَّ الْقَوْمَ قَرْحٌ مِّثْلُهٗ وَتِلْكَ الْاَیَّامُ نُدَاوِلُهَا بَیْنَ النَّاسِ وَلِیَعْلَمَ اللّٰهُ الَّذِیْنَ اٰمَنُوْا وَیَتَّخِذَ مِنْكُمْ شُهَدَآءَ وَاللّٰهُ لَا یُحِبُّ الظّٰلِمِیْنَ ۟

Iny-yamsaskum qarhum faqad massal qawma qarhum misluh; wa tilkal ayyaamu nudaawiluhaa bainan naasi wa liya'lamal laahul lazeena aamanoo wa yattakhiza minkum shuhadaaa'; wallaahu laa yuh ibbuz zaalimeen

“If a wound hath touched you, be sure a similar wound hath touched the others. Such days (of varying fortunes) We give to men and men by turns: that Allah may know those that believe, and that He may take to Himself from your ranks Martyr-witnesses (to Truth). And Allah loveth not those that do wrong.”
