Sahih al-Bukhari 5983

Musa ibn Talha was heard to relate that Abu Ayyub said, "It was said, 'Messenger of Allah, tell me an action which will ensure my entrance into the Garden'" Musa ibn Talha related that Abu Ayyub al-Ansari related that a man said, "Tell me an action which will ensure my entrance into the Garden." The people said, "What does he want? What is wrong with him?" The Messenger of Allah, may Allah bless him and grant him peace, said, "What he wants is to know something." The Prophet, may Allah bless him and grant him peace, said, "Worship Allah and do not associate anything else with him. Establish the prayer and pay the zakat and maintain ties of kinship. Leave it!" He said, "It seems that the Prophet, may Allah bless him and grant him peace, was riding his camel."
