You who believe! be upholders of justice, bearing witness for Allah alone, even against yourselves or your parents and relatives. Whether they are rich or poor, Allah is well able to look after them. Do not follow your own desires and deviate from the truth. If you twist or turn away, Allah is aware of what you do. (Surat an-Nisa’, 135)
O YOU who have attained to faith! Be ever steadfast in your devotion to God, bearing witness to the truth in all equity; and never let hatred of any-one lead you into the sin of deviating from justice. Be just: this is closest to being God-conscious. And remain conscious of God: verily, God is aware of all that you do.(Surah AlMaida, 8)
