Ibn Mas'ud said: "I asked the Messenger of Allah: 'O Messenger of Allah! Which is the most virtuous of deeds?' He said: 'Salat during its appropriate time.' I said: 'Then what, O Messenger of Allah?' He said: 'Being dutiful to one's parents.' I said: 'Then what, O Messenger of Allah?' He said: 'Jihad in the cause of Allah.' Then the messenger of Allah was silent, and if I had asked him more, he would have told me more.'"
