Machine translationRead the Arabic original
The questioner : Swearing by other than Allah is shirk in lordship. What is the aspect of that?
The Shaykh : Brother, yes. Swearing by other than Allah is shirk in lordship. If you stand up and say, "May the best be..."
The questioner : What is the aspect of that?
The Shaykh : Because swearing by a thing means exalting that thing. So, one has given this thing by which he swears an exaltation that it deserves to be sworn by, like the exaltation of Allah.
