Always keep it fair!
Shaykhul Islaam Ibn Taymiyyah stated:
“The Sunnah is protected by the truth, truthfulness and justice. It’s not protected by lies and oppression. If the person refutes falsehood with falsehood and confronts innovation with innovation, this is what the Salaf and Imaams (of the religion) have blamed.”
[Darut Ta’aarud 7/182]
