Musnad Ahmad 3973

It was narrated that Ibn Mas'ood said: I said: O Messenger of Allah, which deed is most beloved to Allah, may He be glorified and exalted? He said: “Offering prayer on time.” I said: Then what? He said: “Honouring one's parents." I said: Then what? He said: “Then jihad for the sake of Allah.” And if I had asked for more. he would have given me more.
