Standing for fairness when it costs you
The verse names exactly who you might be tempted to protect.
۞ يَـٰٓأَيُّهَا ٱلَّذِينَ ءَامَنُوا۟ كُونُوا۟ قَوَّٰمِينَ بِٱلْقِسْطِ شُهَدَآءَ لِلَّهِ وَلَوْ عَلَىٰٓ أَنفُسِكُمْ أَوِ ٱلْوَٰلِدَيْنِ وَٱلْأَقْرَبِينَ ۚ إِن يَكُنْ غَنِيًّا أَوْ فَقِيرًا فَٱللَّهُ أَوْلَىٰ بِهِمَا ۖ فَلَا تَتَّبِعُوا۟ ٱلْهَوَىٰٓ أَن تَعْدِلُوا۟ ۚ وَإِن تَلْوُۥٓا۟ أَوْ تُعْرِضُوا۟ فَإِنَّ ٱللَّهَ كَانَ بِمَا تَعْمَلُونَ خَبِيرًا
Yā ayyuha-lladhīna āmanū kūnū qawwāmīna bi-l-qisṭi shuhadā'a lillāhi wa law ʿalā anfusikum awi-l-wālidayni wa-l-aqrabīn…
“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.1 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.”
