Imam Ali (AS) said:
لَمْ يَكُنْ لِأَحَدٍ فِىَّ مَهْمَزٌ وَ لالِقائلٍ فِىَّ مَغْمَزٌ، الَـذَّلـيلُ عِنْدى عَـزيزٌ حَتّى اخُذَ الْحَـقَّ لَـهُ، وَ الْقَوِىُّ عِنْدى ضَعيفٌ حَتّى اخُذَ الْحَـقَّ مِنْهُ. رَضينا عَنِ اللّه ِ قَـضاءَهُ وَ سَلَّمْنا لِلّه أَمْـرَهُ
The low is dear in my view till I secure (his) right for him while the strong is in my view weak till I take (others’) rights from him. We are happy with the destiny ordained by Allah and have submitted to the command of Allah.
