Surah An-Nisa, verse 64

وَمَآ أَرْسَلْنَا مِن رَّسُولٍ إِلَّا لِيُطَاعَ بِإِذْنِ ٱللَّهِ ۚ وَلَوْ أَنَّهُمْ إِذ ظَّلَمُوٓا۟ أَنفُسَهُمْ جَآءُوكَ فَٱسْتَغْفَرُوا۟ ٱللَّهَ وَٱسْتَغْفَرَ لَهُمُ ٱلرَّسُولُ لَوَجَدُوا۟ ٱللَّهَ تَوَّابًا رَّحِيمًا ﴿٦٤﴾

4:64 We did not send any Messenger but to be obeyed by Allah’s permission. If only they had come to you [O Prophet] – after wronging themselves – and had asked Allah for forgiveness, and the Messenger had asked for forgiveness for them, they would have found Allah Accepting of Repentance, Most Merciful
