Sunan An-Nasai, Chapter: The Book of Salah

that a man said: "O Messenger of Allah, tell me of a deed that will gain me admittance to Paradise." The Messenger of Allah (saw) said: 'Worship Allah and do not associate anything with Him, establish the Salah, pay the Zakah and uphold the ties of kinship. Let go!'" - as if he was riding his camel.* (Sahih) *As if he was riding his camel and the man had grabbed hold of its reins to ask this question.
