Establishing the Proof: How Is It Established, and Is Understanding It Necessary?

The questioner : Regarding the establishment of the proof, is it sufficient to establish it? Is it sufficient to make it clear to people, or is it necessary that...?

The Shaykh : What do you say if a man from the non-Arabic speaking lands is brought to you and you say, "O this disbeliever, fear Allah and submit to Islam"? What is this? Has the proof been conveyed? Also, we call it a proof, but there is no proof until he understands it.
