It was narrated that 'Abdullah bin Mas'ood said:

I asked the Messenger of Allah (ﷺ): O Messenger of Allah, which deed is best? He said: "Prayer offered on time." I said: Then what, O Messenger of Allah? He said: "Honouring one's parents." I said: Then what, O Messenger of Allah? He said: Jihad for the sake of Allah. Then I fell silent and if I had asked the Messenger of Allah (ﷺ) for more, he would have given me more.
