ADNAN OKTAR: It is an attribute of the system of the Mahdi; he identifies the unbelief and perversion very well, and beats the hammer on them very well; hammers down the idols and smashes them down one by one. 

However I have been telling about the Prophet Abraham (a.s.) possessing Ilm al-Ladun  but even though some of viewer, reader, listener brothers understood, some could not understand. Look, there is a very practical implementation in the Prophet Abraham (a.s.). People ask me "Master, what is ilm al-ladun? can you please teach us, explain it to us."  Allah shows that to us in the Qur'an.  The Qur'an tells us that the Prophet Abraham (a.s) looks at the skies, looks at the stars and says "I am ill". That is a hidden knowledge (ilm al-ladun), the Prophet Abraham (a.s.) is not someone who would look at the stars and make a decision based on them. Niether is he a person who would say "I am ill". Why would he say I am ill to the unbelievers? They are not doctors, so why would he tell them that he is ill.  Why would he look at the start? That is a hidden knowledge.

The Prophet Joseph (a.s.)'s hiding the goblet and placing them in the saddlebags  is through hidden knowledge. Seemingly such an act is a felony, but inwardly what he did was just, right? This is a felony according to the people there. It is a felony according to that mentality, but inwardly this is just, this is correct. What does Hazrat Joseph (a.s.) say; let me explain it another day in details. However I have given the first example about the hidden knowledge. What does the Prophet Abraham (a.s.) do in the second? He broke down all the idols and leaves the biggest one sound, he doesn't break it down. He doesn't break it, he praises it and hangs the hammer around its neck. Look he attaches the hammer on his neck, he attaches the system with which he smashed everything down on its neck.  And says; "this one broke it, this idol has smashed them".  By that the men there were served with a predicament.. They realize it in their hearts but they object in appearance, right? That is ilm al-ladun (hidden knowledge), that is esoteric knowledge insha'Allah. At that time for instance he was thus able to save himself very easily. Right? Insha'Allah.
