﴿ وَلَئِنْ أَصَٰبَكُمْ فَضْلٌۭ مِّنَ ٱللَّهِ لَيَقُولَنَّ كَأَن لَّمْ تَكُنۢ بَيْنَكُمْ وَبَيْنَهُۥ مَوَدَّةٌۭ يَٰلَيْتَنِى كُنتُ مَعَهُمْ فَأَفُوزَ فَوْزًا عَظِيمًۭا ﴾

“But if good fortune comes to you from God, such a person is sure to say - just as if there had never been any question of love between you and him -: "Oh, would that I had been with them, and thus had a [share in their] mighty triumph!"”
