وَكَأَيِّن مِّن نَّبِىٍّۢ قَٰتَلَ مَعَهُۥ رِبِّيُّونَ كَثِيرٌۭ فَمَا وَهَنُوا۟ لِمَآ أَصَابَهُمْ فِى سَبِيلِ ٱللَّهِ وَمَا ضَعُفُوا۟ وَمَا ٱسْتَكَانُوا۟ ۗ وَٱللَّهُ يُحِبُّ ٱلصَّٰبِرِينَ
And with how many a prophet have there been a number of devoted men who fought (beside him). They quailed not for aught that befell them in the way of Allah, nor did they weaken, nor were they brought low. Allah loveth the steadfast.
