إِن تَتُوبَا إِلَى اللَّهِ فَقَدْ صَغَتْ قُلُوبُكُمَا وَإِن تَظَاهَرَا عَلَيْهِ فَإِنَّ اللَّهَ هُوَ مَوْلَاهُ وَجِبْرِيلُ وَصَالِحُ الْمُؤْمِنِينَ وَالْمَلَائِكَةُ بَعْدَ ذَلِكَ ظَهِيرٌ
If the two of you repent to Allah... for your hearts have certainly swerved, and if you back each other against him, then [know that] Allah is indeed his guardian, and his supporters are Gabriel, the righteous among the faithful and, thereafter, the angels.
