It is narrated from Hazrat Abu Hurairah (may Allah be pleased with him) that a Bedouin came to the service of the Prophet (peace and blessings be upon him) and said, "O Messenger of Allah (peace and blessings be upon him), tell me of an action which, if I act upon it, I will enter Paradise?" The Prophet (peace and blessings be upon him) said: "Worship Allah, do not associate anything with Him, establish the obligatory prayers, pay the obligatory zakat, and fast in Ramadan." The Bedouin said, "By Allah, I will neither decrease nor increase anything from this on my own." When he left, the Prophet (peace and blessings be upon him) said: "Whoever wants to see a man of Paradise, let him look at this one."
