Is it permissible to swear by: (By the truth of 'Amr)?
Machine translationRead the Arabic original
The questioner : Is swearing by "the truth of 'Amr" swearing by something other than Allah?
The Shaykh : Swearing by "the truth of 'Amr" depends on the intention of the one swearing. If he intends by "truth" the truth of Allah, the Exalted, then there is absolutely no harm in it, because he is swearing by Allah. If he intends by "truth" a conceptual meaning, such as correctness, for example, it is also permissible, because it refers back to the first meaning. However, if he intends a material thing, it is not permissible, because he is swearing by something other than Allah. In this case, it is said: "Actions are only by intentions."
