Sura al-Taḥrīm 66:4

إِن تَتُوبَآ إِلَى ٱللَّـهِ فَقَدْ صَغَتْ قُلُوبُكُمَا وَإِن تَظَٰهَرَا عَلَيْهِ فَإِنَّ ٱللَّـهَ هُوَ مَوْلَىٰهُ وَجِبْرِيلُ وَصَٰلِحُ ٱلْمُؤْمِنِينَ وَٱلْمَلَٰٓئِكَةُ بَعْدَ ذَٰلِكَ ظَهِيرٌ

in tatūbā ilā allāhi fa-qad ṣaghat qulūbukumā wa-in taẓāharā ʿalayhi fa-inna allāha huwa mawlāhu wa-jibrīlu wa-ṣāliḥu l-muʾminīna wa-l-malāʾikatu baʿda dhālika ẓahīrun

If ye two turn in repentance to Him, your hearts are indeed so inclined; But if ye back up each other against him, truly Allah is his Protector, and Gabriel, and (every) righteous one among those who believe,- and furthermore, the angels - will back (him) up.
