Read and reflect on verse 566 from Surah An-Nisaa: 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 -: ...
وَلَئِنْ أَصَابَكُمْ فَضْلٌ مِنَ اللَّهِ لَيَقُولَنَّ كَأَنْ لَمْ تَكُنْ بَيْنَكُمْ وَبَيْنَهُ مَوَدَّةٌ يَا لَيْتَنِي كُنْتُ مَعَهُمْ فَأَفُوزَ فَوْزًا عَظِيمًا
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!"
