The prescription of As-Salat (the prayer)

 201. Anas bin Maik narrated: We were forbidden to ask the Messenger of Allah salla alayhi wa sallam (without the genuine need). Therefore, we liked it when an intelligent person from the dwellers of the desert came and asked him while we listened. A man from the dwellers of the desert came (to the Prophet salla alayhi wa sallam) and said: ´´O Muhammad, your messenger came to us and told us your claim that Allah had sent you (as a Prophet). He salla alayhi wa sallam said: ´´He told the truth.´´ He asked: ´´Who created the heaven?´´ He salla alayhi wa salllam replied: ´´Allah.´´ He aksed: ´´Who created the earth?´´ He salla alayhi wa sallam replied: ´´Allah.´´ He aksed: ´´Whi raied these mountains and who created in them whatever is created?´´ He salla alayhi wa sallam replied: ´´Allah.´´ Upon this he remarked: ´´By Him Who created the heaven and created the earth and raised mountains, has Allah sent you?´´ He salla alayhi wa salalm said: ´´Yes.´´ He said: ´´Your messenger also claimed that five Salat (prayers) during the day and the night are obligatory on us.´´ He salla alayhi wa sallam said: ´´He told you the truth.´´ He said: ´´By him Who sent you. is it Allah Who ordered you this?´´ He salla alayhi wa sallam said: ´´Yes.´´ He said: ´´Your messenger claimed that Zakat is obligatory on our wealth.´´ He salla alayhi wa sallam said: ´´He told the truth.´´ He said: ´´By Him Who sent you, is it AllahWho ordered you this?´´ He salla alayhi wa sallam said: ´´Yes.´´ He said: ´´Your messenger claimed that it is obligatory on us to fast every yeart during the month of Ramadan.´´ He salla alayhi wa sallam said: ´´He told the truth.´´ He said: ´´By Him Who has sent you, is it Allah Who ordered you thi?´´ He salla alayhi wa sallam said: ´´Yes.´´ He said: ´´Your messenger also claimed that Hajj (pilgrime) to the House (of Ka´bah) is made obligatory on him who can afford the journey.´´ He salla alayhi wa sallam said: ´´Yes.´´ The narrator said that the bedouin set off (at the conclusion of this answer), saying: ´´By Him Who sent you with the truth, I would neither add to them nor diminish anything of them.´´ Upon this, the Prophet salla alayhi wa sallam remarked: ´´If he is truthful, he will enter Jannah.´´
