The following Du'a from Imam Jewad (a) (9th successor) talks about injusticeI find illuminating in that people wonder what of Islam was lost with martyrdom of Imam Hussain (a), well it's the justice side - the human rights side included.
اَللَّهُمَّ إِنَّ ظُلْمَ عِبَادِكَ قَدْ تَمَكَّنَ فِي بِلاَدِكَ
allahumma inna zulma `ibadika qad tamakkana fi biladika
O Allah, the persecutions against Your servants have become so prevalent in Your lands
حَتَّىٰ امَاتَ ٱلْعَدْلَ
hatta amata al`adla
that it has put an end to justice,
وَقَطَعَ ٱلسُّبُلَ
wa qata`a alssubula
and cut off the paths [to guidance]
وَمَحَقَ ٱلْحَقَّ
wa mahaqa alhaqqa
It has wiped out the truth
وَابْطَلَ ٱلصِّدْقَ
wa abtala alssidqa
and nullified truthfulness
وَاخْفَىٰ ٱلْبِرَّ
wa akhfa albirra
It has concealed righteousness ,
وَاظْهَرَ ٱلشَّرَّ
wa azhara alshsharra
and made evil become manifest
وَاخْمَدَ ٱلتَّقْوَىٰ
wa akhmada alttaqwa
It has quelled God-consciousness
وَازَالَ ٱلْهُدَىٰ
wa azala alhuda
and made guidance disappear
وَازَاحَ ٱلْخَيْرَ
wa azaha alkhayra
It has made goodness distant
وَاثْبَتَ ٱلضَّيْرَ
wa athbata alddayra
and established wrong
وَانْمَىٰ ٱلْفَسَادَ
wa anma alfasada
It has caused corruption to spread
وَقَوَّىٰ ٱلْعِنَادَ
wa qawwa al`inada
and strengthened deviance,
وَبَسَطَ ٱلْجَوْرَ
wa basata aljawra
It has spread tyranny
وَعَدَىٰ ٱلطَّوْرَ
wa `ada alttawra
and transgressed the limits.
اَللَّهُمَّ يَا رَبِّ لاَ يَكْشِفُ ذٰلِكَ إِلاَّ سُلْطَانُكَ
allahumma ya rabbi la yakshifu dhalika illa sultanuka
O Allah, my Lord, no one can remove that [injustice] except Your authority
وَلاَ يُجِيرُ مِنْهُ إِلاَّ ٱمْتِنَانُكَ
wa la yujiru minhu illa imtinanuka
and nothing can rescue from it except Your favour.
اَللَّهُمَّ رَبِّ فَٱبْتُرِ الظُّلْمَ

O Allah, my Lord, cut off oppression
وَبُثَّ جِبَالَ ٱلْغَشْمِ

uproot the enmity of the people of tyranny,
وَالْبِسْهُمُ ٱلْحَوْرَ بَعْدَ ٱلْكَوْرِ
wa albishumu alhawra ba`da alkawri
and clothe them with loss after excess.
وَعَجِّلِ ٱللَّهُمَّ إِلَيْهِمُ ٱلْبَيَاتَ
