Sayyiduna Abu Ayyub Ansari (may Allah be pleased with him) narrates: A Bedouin came before the Prophet (peace and blessings be upon him). He caught hold of the reins of your camel and said: O Messenger of Allah! Tell me about a deed that will admit me to Paradise and save me from Hell. The narrator says: The Prophet (peace and blessings be upon him) looked at the faces of his companions and stopped his camel. He said: This person has been granted success. (The narrator is in doubt, perhaps these are the words:) He has been guided. Do not associate anyone with Allah, perform the prayer, pay the zakat, maintain the ties of kinship, and (now) let go of the camel.
