What is the most important advice the Prophet Muhammad (saw) gave on how to live a life of righteousness and piety?
 Narrated Ibn Mas`ud:                     A man asked the Prophet "What deeds are the best?" The Prophet said: (1) To perform the (daily compulsory) prayers at their (early) stated fixed times, (2) To be good and dutiful to one's own parents. (3) and to participate in Jihad in Allah's Cause."
