Machine translationRead the Arabic original
The questioner : May Allah bless you.
The Shaykh : Yes, he sees that this is Satan's share. He sees that one does not turn away except from the right side. Is it for the sake of the action? No, it is for the sake of the belief that one does not turn away except from the right side. This is where he gains a share, because you believed that something permissible is not permissible.
The presenter : We support it.
The Shaykh : Yes.
