(Ashoora) 42 : 43
وَلَمَنْ صَبَرَ وَغَفَرَ إِنَّ ذَٰلِكَ لَمِنْ عَزْمِ الْأُمُورِ
And surely, if anyone shows patience and forgiveness, indeed, it is from the confirmed determination of affairs.
That means by seeing the Hereafter, if anyone is showing patience and is forgiving, it is from the confirmed determination of affairs. See explanation 9: 51; 31: 16-17, and 32: 24.
