O you who have believed, be persistently standing firm in justice, witnesses for Allāh, even if it be against yourselves or parents and relatives. Whether one is rich or poor, Allāh is more worthy of both. So follow not [personal] inclination, lest you not be just. And if you distort [your testimony] or refuse [to give it], then indeed Allāh is ever, of what you do, Aware.

O you who believe, be upholders of justice - witnesses for Allah, even though against (the interest of) your selves or the parents, and the kinsmen. One may be rich or poor, Allah is better caretaker of both. So do not follow desires, lest you should swerve. If you twist or avoid (the evidence), then, Allah is all-aware of what you do.
