Syedna Abu Hurairah (may Allah be pleased with him) narrates that the Messenger of Allah (peace and blessings be upon him) said: Whoever attributes to me something which I have not said, let him prepare his abode in the Fire. Whoever is consulted by his Muslim brother, but gives him advice without wisdom and uprightness, then he has betrayed him. And whoever gives a legal verdict without proper investigation, then its sin will be upon the one who gave the verdict.
