إِن يَمْسَسْكُمْ قَرْحٌ فَقَدْ مَسَّ الْقَوْمَ قَرْحٌ مِّثْلُهُ وَتِلْكَ الأيَّامُ نُدَاوِلُهَا بَيْنَ النَّاسِ وَلِيَعْلَمَ اللّهُ الَّذِينَ آمَنُواْ وَيَتَّخِذَ مِنكُمْ شُهَدَاء وَاللّهُ لاَ يُحِبُّ الظَّالِمِينَ
[3:140]
If a wound has afflicted you (at Ohud), a wound like it has also afflicted the (unbelieving) people; and We bring these days to men by turns, and that Allah may know those who believe and take witnesses from among you; and Allah does not love the unjust.
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.
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.
