It is narrated on the authority of Abu Ayyub (RA) that a man came to the Prophet (ﷺ) 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 (the Holy Prophet) 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 Messenger of Allah (ﷺ) remarked: If he adheres to what he has been ordered to do, he would enter Paradise.
