إِن تَتُوبَآ إِلَى ٱللَّهِ فَقَدْ صَغَتْ قُلُوبُكُمَا ۖ وَإِن تَظَـٰهَرَا عَلَيْهِ فَإِنَّ ٱللَّهَ هُوَ مَوْلَىٰهُ وَجِبْرِيلُ وَصَـٰلِحُ ٱلْمُؤْمِنِينَ ۖ وَٱلْمَلَـٰٓئِكَةُ بَعْدَ ذَٰلِكَ ظَهِيرٌ
In tatoobaaa ilal laahi faqad saghat quloobukumaa wa in tazaaharaa 'alihi fa innal laaha huwa mawlaahu wa jibreelu wa saalihul mu'mineen; walma laaa'ikatu ba'dazaalika zaheer
If both of you [wives] repent to God––for your hearts have deviated––[all will be well]; if you collaborate against him, [be warned that] God will aid him, as will Gabriel and all righteous believers, and the angels too will back him.
If you two turn to God in repentance — for your hearts have inclined away — that is best; but if you join forces against him, then God himself is his protector, and so are Gabriel and the righteous among the believers; and beyond that, the angels stand behind him.
