HOW TO DEAL WITH INJUSTICE H 51 "After me there will be discrimination and you will observe things of which you will disapprove." A Companion asked: 'Messenger of Allah, praise and peace be upon him, what is your directive in such circumstances?' He said: 'Do what is right - upon you - and supplicate to Allah for (the right of) yours.'" R 51 Bukhari and Muslim with a chain up to Ibn Mas'ud who related that the Prophet, praise and peace be upon him, said this.
51- وعن ابن مسعود رضي الله عنه : أن رَسُول الله صلى الله عليه وآله وسلم ، قَالَ : "إنَّهَا سَتَكونُ بَعْدِي أثَرَةٌ وأُمُورٌ تُنْكِرُونَها !" قَالُوا : يَا رَسُول الله ، فَمَّا تَأْمُرُنا ؟ قَالَ : "تُؤَدُّونَ الْحَقَّ الَّذِي عَلَيْكُمْ ، وَتَسأَلُونَ الله الَّذِي لَكُمْ" مُتَّفَقٌ عَلَيهِ . " وَالأَثَرَةُ" : الانْفِرادُ بالشَّيءِ عَمنَ لَهُ فِيهِ حَقٌّ .
