Al-Maẓālim (Arabic: المظالم, romanized: al-maẓālim, lit.
'injustices, grievances') were an ancient pre-Islamic institution that was adopted by the Abbasid Caliphate in the eighth century CE.
The main purpose of the maẓālim courts was to give ordinary people redress.
[1] Al-Maẓālim, or the sultan's court, was distinguished from the shurṭa or police courts.
