Musnad Ahmad 1390
Malik narrated from his paternal uncle, from his father, that he heard Talhah bin `Ubaidullah say:
A Bedouin came to the Prophet (ﷺ) and said: “O Messenger of Allah(ﷺ), what is Islam?” He said: `Five prayers every day and night.` He said: “Do l have to do anything other than that?” He said: “No.” He asked him about fasting and he said: “Fasting (the month of) Ramadan.” He said: “Do I have to do anything other than that?” He said: “No.” He mentioned zakah and said: “Do I have to do anything other than that?” He said: “No.” He said: “By Allah, I will do no more and no less than that.” The Messenger of Allah (ﷺ) said: “He will prosper, if he means what he says.”
