A man from among the people of Najd with disheveled hair came to the Messenger of Allah (ﷺ). The humming sound of his voice could be heard but what he was saying could not be understood. He came closer and it was then known that he was asking about Islam. The Messenger of Allah (ﷺ) said: Five times of prayer each day and night: He asked: Must I observe any more than them? He replied: No, unless you do it voluntarily. He (Talhah) said that the Messenger of Allah (ﷺ) mentioned fasting during the month of Ramadan. He asked: Must I observe anything else? He replied: No, unless you do it voluntarily. The Messenger of Allah (ﷺ) mentioned Zakat to him. He asked: Must I pay anything else? He replied: No, unless you do it voluntarily. The man then turned away saying: I swear by Allah, I shall not add anything to this or fall short of it. The Messenger of Allah (ﷺ) said: The man will be successful if he speaks truth.
