Models of justice in his Sunnah and conducts:
Firstly, his warning of enslavement of people: The Prophet (blessing and peace be upon him) implanted the value of justice in his followers, he said a warning of enslavement of people: “Not one of you say to my servant “slave” and to my female servant “female slave”, all of you and all your wives be servants of Allah, but say my lad and my maid and my young and my young girl.”

Secondly, his banning of racial discrimination: He said: “You are sons
of Adam, and Adam came from dust. Let the people cease to boast about
their ancestors. They are merely fuel in hell; or they will certainly be
of less account with Allah than the beetle which rolls dung with its
nose.” 4 The Prophet (blessing and peace be upon him) ranted severely
with Abu Dhar when he mocked the mother of Bilal.
