Surah At-Tahrim (The Prohibition), Verse 4

اِنْ تَتُوْبَاۤ اِلَی اللّٰهِ فَقَدْ صَغَتْ قُلُوْبُكُمَا وَاِنْ تَظٰهَرَا عَلَیْهِ فَاِنَّ اللّٰهَ هُوَ مَوْلٰىهُ وَجِبْرِیْلُ وَصَالِحُ الْمُؤْمِنِیْنَ وَالْمَلٰٓىِٕكَةُ بَعْدَ ذٰلِكَ ظَهِیْرٌ ۟

In tatoobaaa ilal laahi faqad saghat quloobukumaa wa in tazaaharaa 'alaihi fa innal laaha huwa mawlaahu wa jibreelu wa saalihul mu'mineen; wal malaaa'ikatu ba'da zaalika zaheer

“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.”

Quran 66:4 (Yusuf Ali Translation)
