It is narrated from Sayyiduna Talhah bin Ubaidullah (may Allah be pleased with him) that a Bedouin came to the Messenger of Allah (peace and blessings of Allah be upon him) with disheveled hair. He said: "O Messenger of Allah! How many prayers has Allah made obligatory upon me?" He replied: "Five prayers, and fasting (is also) obligatory." After that, the Messenger of Allah (peace and blessings of Allah be upon him) informed him of the rulings of the religion. So he said: "By Him Who has honored you, I will neither decrease nor increase anything from these obligations." The Messenger of Allah (peace and blessings of Allah be upon him) said: "By his father, if he has spoken truthfully from his heart, he has succeeded." ... Or he said: "By his father, if he has spoken the truth, he will enter Paradise."
