It is narrated on the authority of Abu Ayyub that a man came to the Prophet (pbuh) and said: Direct me to a deed which draws me near to Paradise and takes me away from the Fire (of Hell). 

Upon this  he ( Prophet pbuh) said: You worship Allah and never associate anything with Him, establish prayer, and pay Zakat and do good to your kin. When he turned his back, the prophet (pbuh) remarked: 

 If he adheres to what he has been ordered to do, he would enter Paradise. Hadith
