Surah An-Nisa, Verse 64

وَمَآ أَرۡسَلۡنَا مِن رَّسُولٍ إِلَّا لِيُطَاعَ بِإِذۡنِ ٱللَّهِۚ وَلَوۡ أَنَّهُمۡ إِذ ظَّلَمُوٓاْ أَنفُسَهُمۡ جَآءُوكَ فَٱسۡتَغۡفَرُواْ ٱللَّهَ وَٱسۡتَغۡفَرَ لَهُمُ ٱلرَّسُولُ لَوَجَدُواْ ٱللَّهَ تَوَّابٗا رَّحِيمٗا٦٤

wamā arsalnā min rasūlin illā liyuṭāʿa bi-idh'ni l-lahi walaw annahum idh ẓalamū anfusahum jāūka fa-is'taghfarū l-laha wa-is'taghfara lahumu l-rasūlu lawajadū l-laha tawwāban raḥīman

And We did not send any messenger except to be obeyed by permission of Allāh. And if, when they wronged themselves, they had come to you, [O Muḥammad], and asked forgiveness of Allāh and the Messenger had asked forgiveness for them, they would have found Allāh Accepting of Repentance and Merciful.
