Flee like you would flee from a lion
In The Name of Allah, The Most Merciful, The Bestower of Mercy.
Imam Muhammad Ibn Salih, may Allah have mercy upon them, said:
O student of knowledge! It is obligated to you to abandon (blameworthy) debate and argumentation because debate and argumentation is a means to cutting off the path to what is correct, makes a person speak to give the upper hand to himself. Even if the truth is made clear to him, you will find him either rejecting it or misconstruing the truth -out of disliking it- to give himself the upper hand and compel his opponent to accept his statement. Therefore, if you notice (blameworthy) debate and argumentation from your brother when the truth is very clear, but he does not follow it, flee from him like you would flee from a lion, and say, “I do not have anything other than the truth I have mentioned to you”.
