وَلَئِنْ أَصَٰبَكُمْ فَضْلٌۭ مِّنَ ٱللَّهِ لَيَقُولَنَّ كَأَن لَّمْ تَكُنۢ بَيْنَكُمْ وَبَيْنَهُۥ مَوَدَّةٌۭ يَٰلَيْتَنِى كُنتُ مَعَهُمْ فَأَفُوزَ فَوْزًا عَظِيمًۭا
And if a bounty from Allah befell you, he would surely cry, as if there had been no love between you and him: Oh, would that I had been with them, then should I have achieved a great success!
Surah An-Nisaa(4:73)
