(Ashoora) 42 : 43
وَلَمَنْ صَبَرَ وَغَفَرَ إِنَّ ذَٰلِكَ لَمِنْ عَزْمِ الْأُمُورِ
And surely 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.
