وَلَا تَهِنُوا وَلَا تَحْزَنُوا وَأَنْتُمُ الْأَعْلَوْنَ إِنْ كُنْتُمْ مُؤْمِنِينَ ١٣٩
So lose not heart, nor fall into despair: For ye must gain mastery if ye are true in Faith.
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 ١٤٠
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.
3:141
وَلِيُمَحِّصَ اللَّهُ الَّذِينَ آمَنُوا وَيَمْحَقَ الْكَافِرِينَ ١٤١
Allah's object also is to purge those that are true in Faith and to deprive of blessing Those that resist Faith.
3:142
أَمْ حَسِبْتُمْ أَنْ تَدْخُلُوا الْجَنَّةَ وَلَمَّا يَعْلَمِ اللَّهُ الَّذِينَ جَاهَدُوا مِنْكُمْ وَيَعْلَمَ الصَّابِرِينَ ١٤٢
Did ye think that ye would enter Heaven without Allah testing those of you who fought hard (In His Cause) and remained steadfast?
3:143
وَلَقَدْ كُنْتُمْ تَمَنَّوْنَ الْمَوْتَ مِنْ قَبْلِ أَنْ تَلْقَوْهُ فَقَدْ رَأَيْتُمُوهُ وَأَنْتُمْ تَنْظُرُونَ ١٤٣
Ye did indeed wish for death before ye met him: Now ye have seen him with your own eyes, (And ye flinch!)
