إِن يَمْسَسْكُمْ قَرْحٌ فَقَدْ مَسَّ الْقَوْمَ قَرْحٌ مِّثْلُهُ ۚ وَتِلْكَ الْأَيَّامُ نُدَاوِلُهَا بَيْنَ النَّاسِ وَلِيَعْلَمَ اللَّهُ الَّذِينَ آمَنُوا وَيَتَّخِذَ مِنكُمْ شُهَدَاءَ ۗ وَاللَّهُ لَا يُحِبُّ الظَّالِمِينَ (140)
(3:140) If a wound has befallen you a similar wound has already befallen the people who are opposed to you. *100 We make such movements to men in turn so that Allah might mark out those who are the true men of faith and select from among you those who do really bear witness (to the Truth): *101 for Allah does not love the wrong-doers,
*100). This alludes to the Battle of Badr. The intention is to point out to the Muslims that if the unbelievers were not demoralized by the setback they suffered at Badr then the Muslims should not be disheartened by the setback thev suffered in the Battle of Uhud.
*101). The actual words of this verse, can be interpreted in two ways. One meaning could be that God wanted to select some of them so that He could bestow upon them the honour of martyrdom. The second meaning could be that out of the hotch-potch of true believers and hypocrites which their community consisted of at that moment, God wanted to sift those who were truly His witnesses over all mankind. (See Qur'an 2: 143 - Ed.)
