An-Nisa 4:64

وَمَآ أَرْسَلْنَا مِن رَّسُولٍ إِلَّا لِيُطَاعَ بِإِذْنِ ٱللَّهِ ۚ وَلَوْ أَنَّهُمْ إِذ ظَّلَمُوٓا۟ أَنفُسَهُمْ جَآءُوكَ فَٱسْتَغْفَرُوا۟ ٱللَّهَ وَٱسْتَغْفَرَ لَهُمُ ٱلرَّسُولُ لَوَجَدُوا۟ ٱللَّهَ تَوَّابًا رَّحِيمًا

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.
