The questioner:
Honorable Shaykh, may Allah grant you success, he says: If I know that the one who swears to me by Allah is a liar,
The Shaykh:
Yes.
The questioner:
and does not revere Allah, should I believe him and respond to what he mentioned?
The Shaykh:
No, if you know that he is a liar, do not believe him even if he swears. If you know that he is a liar, [do not believe him]. But if you do not know that he is a liar, then you revere Allah and honor Allah (Mighty and Majestic) and take him at his word.
