Musnad Ahmad Hadith 12457

Anas (may Allah be pleased with him) says that (since) we were forbidden in the Qur'an from asking the Messenger of Allah (ﷺ) too many questions, we used to wish in our hearts that some intelligent Bedouin would come and ask the Prophet (ﷺ) about some issue and we would listen. So (once) a Bedouin came and (presented himself before the Prophet, peace and blessings be upon him, and) said: "Your messenger came to us and said that you claim Allah has made you a Prophet?" The Prophet (ﷺ) said: "He spoke the truth." The Bedouin said: "Who created the heavens, the earth, and the mountains?" The Prophet (ﷺ) said: "Allah did." The Bedouin said: "I ask you by the One who created the heavens and the earth and established the mountains (tell me), has Allah really sent you as a Messenger?" The Prophet (ﷺ) said: "Yes!" The Bedouin said: "Your messenger says that five prayers are obligatory upon us in the day and night." The Prophet (ﷺ) said: "He spoke the truth." The Bedouin said: "I ask you by Allah, the One who sent you as a Messenger (tell me), did Allah command you this?" The Prophet (ﷺ) said: "Yes!" The Bedouin said: "Your messenger said that zakat is obligatory upon our wealth?" The Prophet (ﷺ) said: "He spoke the truth." He said: "By the One who sent you, did He command you this?" The Prophet (ﷺ) said: "Yes!" He said: "Your messenger also said that fasting for one month in the year is obligatory upon us?" The Prophet (ﷺ) said: "He spoke the truth." The Bedouin said: "I ask you by Allah, the One who made you a Prophet (tell me), did Allah command you this?" The Prophet (ﷺ) said: "Yes!" The Bedouin said: "Your messenger also said that Hajj to the Ka'bah is obligatory upon those among us who are able?" The Prophet (ﷺ) said: "He spoke the truth!" Finally, as the Bedouin turned to leave, he said: "By Allah, the One who sent you with the truth, I will not add to this nor subtract from it at all." The Prophet (ﷺ) said: "If he is truthful, he will enter Paradise."
