Imam Ali (AS) said, Know that injustice is of three kinds: the injustice that is not forgiven, the injustice that is not left [unquestioned], and the injustice that is forgiven without being questioned. As for the injustice that is not forgiven, it is the ascribing of partners to Allah as He, the Most High, says: ‘Verily Allah does not forgive that any partner should be ascribed to Him, but He forgives anything besides that to whomever He wishes. As for the injustice that is forgiven, it is the injustice of a person to himself in committing some small sins. And as for the injustice that is not left unquestioned, it is the injustice of the people on one another. In this case the punishment is severe, not [simply] wounding with knives or striking with whips, rather it is a punishment in comparison to which all this seems small.
الإمامُ عليٌّ (عَلَيهِ الّسَلامُ) : ألا وَ إنَّ الظُّلْمَ ثَلاثَةٌ: فَظُلْمٌ لايُغْفَرُ وَ ظُلْمٌ لايُتْرَكُ وَ ظُلْمٌ مَغْفُورٌ لايُطْلَبُ فَأمّا الظُّلْمُ الَّذي لايُغْفَرُ فَالشِّرْكُ باللّهِ لِقَوْلِهِ تَعالى: إنَّ اللّهَ لايَغْفِرُ أنْ يُشْرَكَ بِهِ وَ يَغْفِرُ مادُونَ ذلِكَ لِمَنْ يَشاءُ وَ أمَّا الظُّلْمُ الَّذي يُغْفَرُ فَظُلْمُ المَرْءِ لِنَفْسِهِ عِنْدَ بَعْضِ الهَناتِ وَ أمَّا الظُّلْمُ الَّذي لايُتْرَكُ فَظُلْمُ العِبادِ بَعْضِهِمْ بَعْضاً اَلعِقابُ هُنالِكَ شَديْدٌ لَيْسَ جَرْحاً بِالمُدى وَلا ضَرْباً بِالسِّياطِ وَ لكِنَّهُ ما يُسْتَصْغَرُ ذلِكَ مَعَهُ
