From Anas bin Malik, he said "We are forbidden to ask something to Rasulullah s.a.w, therefore we always hope that someone "genius" people arrive from some other village who will ask to Rasulullah s.a.w, and we will hear the discussion.
Fortunately, there is one man come from unknown village who go to Rasulullah s.a.w and ask " It has arrived messenger from you majesty (Rasulullah ) to us and the messenger say that you (Rasulullah s.a.w) are the chosen one to be prophet from Allah S.W.T. Rasulullah s.a.w say " True".
Then he ask again to Rasulullah s.a.w" Who are create skies, earth, keep the mountains and other creature (makhluk) inside ? ". Rasulullah s.a.w say" Allah S.W.T".
And then he ask" In the name of greatest Allah S.W.T who are create skies, earth, keep the mountains and other creature (makhluk) inside, is it true that Allah S.W.T has send you (Rasulullah s.a.w) as His Messenger (Prophet)?". Rasulullah s.a.w "Yes".
And then he ask again "Your messenger say that we have to pray ( shalat) five time in a day, to give charity (zakat) from our money (kekayaan), vasting in Ramadhan every year and go to Mecca (Haji) to those who have capability, is it true that you majesty (Rasulullah s.a.w) who has all this task?".
(Then Rasulullah s.a.w answering every portion of questions from genius people, and true is the all of answer from his questions).
Then Anas say that the genius people turn around and also said "In the name of God ( Allah S.W.T) who sent you majesty ( Rasulullah s.a.w) with the truth, then i will not increase and decrease some than these" .
Then Rasulullah s.a.w say " If it's true what he (genius people who asking a lot question) then he will go to heaven (firdaus, Adn, Darussalam, etc)"
