Representatives are in a position of trust during disputes. They must have Taqwa (fear/wariness of offending Allah), defend those they represent by Shar‘y (Islamically lawful) means, and not be motivated by worldly greed to dispute over something that is false. In a Hadith the Prophet (peace be upon him) said,
“Anyone who disputes knowingly about something which is false, will remain in the Displeasure of Allah until they desist.”
And he (peace be upon him) also said,
“Help your brother, whether he is an oppressor or an oppressed. A man said, “O Messenger of Allah! I help him if he is oppressed, but tell me if he is an oppressor, how should I help him?” He (peace be upon him) said, “By preventing him - or forbidding - from oppressing; that is how to help him.”
Representatives should examine claims before entering into disputes and if they see that there is no case, they should abstain from proceeding with them. (Part No. 14; Page No. 279) Similarly, if a representative later discovers that a claim is not valid, they should withdraw from it and not continue. Attorneys should beware of hiding documents that show the truth, as doing so is a type of deception. Allah (Exalted be He) says:
And argue not on behalf of those who deceive themselves. Verily, Allâh does not like anyone who is a betrayer, sinner.
Lo! You are those who have argued for them in the life of this world, but who will argue for them on the Day of Resurrection against Allâh, or who will then be their defender?
May Allah grant us success. May peace and blessings be upon our Prophet Muhammad, his family, and Companions.
