"We were forbidden in the Quran to ask the Prophet about anything not imperative, so we liked it when a wise man from among the people of the desert came and asked him. A man from among the desert people came and said: 'O Muhammad, your messenger came to us and told us that you say that Allah, the Mighty and Sublime, has sent you.' He said: 'He spoke the trought." He said: "Who created the heavens?' He said: Allah. He said: 'Who created the Earth? He said: Allah. He said: 'Who set up the mountains in it?' He said: 'Allah.' He said: Who created beneficial things in them?' He said; 'Allah.' He said: 'By the One Who created the heavens and the Earth, and set up the mountains therein, and created beneficial things in them has Allah sent you?' He said: 'Yes.' He said; 'Your messenger said that we have to offer five prayers each day and night.' He said: 'He spoke the truth.' He said: 'By the One Who sent you, has Allah commanded you to do this?' he said: 'Yes.' He said: 'Your messenger said that we have to pay Zakah on our wealth.' He said: 'He spoke the truth.' He said: 'By the One Who sent you, has Allah commanded you to do this?' He said: 'Yes.' He said; 'Your messenger said that we have to fast the month of Ramadan each year.' He said: 'He spoke the truth . He said: 'By the One Who sent You, has Allah commanded you to do this?' He said: 'yes .' He said: 'Your messenger said that we have to perform Hajj, those who can afford it.' He said: 'He spoke the truth.' He said: 'By the One Who sent you, has Allah commanded you to do this?' he said: 'yes. He said: 'By the One Who sent you with the truth, I will not do more that this or less.' When he left, the Prophet, said: 'If he is sincere, he will certainly enter paradise."'
