Abu Juhayfah narrates from Sayyiduna Ali (may Allah be pleased with him) that jihad is of three kinds: first, that in which the hand prevails, then the tongue, then the heart; when the heart can no longer recognise truth and evil, its upper part is turned downwards.
This is mawquf (stopping at the Companion).
