Hazrat Ibn Abbas (may Allah be pleased with them both) narrates that a Bedouin came to the service of the Noble Prophet (peace and blessings be upon him) and said: "Peace be upon you, O son of Abdul Muttalib." So the Prophet (peace be upon him) replied: "And upon you be peace." Then he said: "Indeed, I am a man from your maternal tribe, the tribe of Banu Sa'd bin Bakr. And I have come to you as a messenger and envoy from my people. And I will ask you some questions. And my questioning will be in a harsh manner. And I will demand oaths from you, so my demand for oaths will be strict." The Prophet (peace be upon him) said: "O brother of Banu Sa'd, ask." The Bedouin said: "Who created you? And is He the one who created the people before you and those who will come after you?" The Prophet (peace be upon him) said: "Allah did." The Bedouin asked: "I ask you by Allah, did He send you as a Messenger?" The Prophet (peace be upon him) said: "Yes." He asked: "Who created the seven heavens and the seven earths, and who spread sustenance between them?" The Prophet (peace be upon him) said: "Allah did." He asked: "I ask you by Allah, did He send you as a Messenger?" The Prophet (peace be upon him) said: "Yes." He said: "So we find written in your Book and your envoy has commanded us that we should perform five prayers in their times during the day and night. I ask you by oath, is this the case?" The Prophet (peace be upon him) said: "Yes." He said: "So we find written in your Book and your envoy has commanded us that we should take out a fixed portion from our wealth and distribute it among our poor. I ask you by oath, is this the case?" The Prophet (peace be upon him) said: "Yes." Then he said: "In any case, I will not ask you about the fifth matter, nor do I have any doubt about it." The narrator says, then he said: "By the One who sent you with the truth, I and those of my people who obey me will certainly adhere to these deeds." Then he returned. So the Messenger of Allah (peace be upon him) laughed so much that his molar teeth became visible. Then the Prophet (peace be upon him) said: "By the One in whose hand is my soul, if he has spoken the truth, he will certainly enter Paradise."
