They would have found Allah Forgiving, Merciful

"And if, when they had wronged themselves, they had but come unto thee and asked forgiveness of Allah, and asked forgiveness of the messenger, they would have found Allah Forgiving, Merciful." Quaan 4:64

وَلَوْ أَنَّهُمْ إِذ ظَّلَمُواْ أَنفُسَهُمْ جَاؤُوكَ فَاسْتَغْفَرُواْ اللَّهَ وَاسْتَغْفَرَ لَهُمُ الرَّسُولُ لَوَجَدُواْ اللَّهَ تَوَّابًا رَّحِيمًا
النساء : ٦٤

O father of Zahrah, O Messenger of Allah, I bear witness that you delivered the Message comprehensively with no deficiency but I had wronged myself, forgive me for disappointing you and not following it completely, please ask the most Forgiving to forgive me and to bestow His mercy on me!
