[4:105-4:106] Surely We have revealed to you the Book with the truth so that you may judge between people by that which God has shown you. And do not be a disputant for traitors. * And pray for forgiveness from God; surely God is ever Forgiving, Merciful.
We did not command you to judge between them blindly, but rather by that which God has shown you, i.e., by that which He unveiled to you from the lights of insight until you understood it by Our teaching you and Our directing you. This is also the case with those who judge in truth from your community.
And do not be a disputant for traitors: i.e., do not defend the masters of worldly concerns, but rather be with the children of [God's] rights. Whoever leans toward whim is a traitor with regards to what has been entrusted to his soul in God-fearingness. Whoever inclines towards the different inclinations of desires is a traitor with regards to what is sought after in life in order to become acquainted with the Protector.
And pray for forgiveness from God for your community, for surely We have protected you in the matter by Our saying: that God may forgive you what is past of your sin [48:2].
