Shaykh Muhammad al-‘Anjaree (may Allaah preserve him) stated:
Listening to news (about a person) without any proof or evidence is oppression. That it is said so and so said this, like some have said to others that I said such and such. Say to this person bring me the recording, or bring the book (that the statement is in) to establish this claim.
To attribute something to a person without any proof and you say: It was stated to me by those who are thiqah without naming who these individuals are, we say name your men to us! Don’t make the matter one that is not clear. It’s a must that you have a proof. You’re speaking about the honor of a person, therefore it’s a must that you bring the proof and evidence! The burden of proof is upon the claimant. This is the Judgment. Indeed the judgment is for Allaah. Use the Sharee’ah as a judge regarding your statement!
Bring me an evidence by mentioning those who are thiqah, so and so the son of so and so, or the recording, or the book (where the statement is written). If you don’t have the ability to bring this, then you are a Kadh-dhaab (liar)! If you don’t have the ability to bring this then you are a liar with clear lies. There is no possibility for interpretation. Say so and so the son of so and so (said), if not then my reckoning with all of those who spoke will be in front of Allaah. I want from the good deeds of these individuals, for I will be in need in that situation.
