Musnad Abu Ya'la al-Mawsili 152:261

Abu Khaythama narrated to us, Ahmad ibn Ishaq narrated to us, Abd al-Aziz ibn Muslim narrated to us, Abu Ishaq narrated to us, from Abu al-Ahwas, from Abdullah, who said: We said, "O Messenger of Allah, which deeds are most beloved to Allah?" He said, "You perform the prayers at their appointed times." He said, "I said, 'Then what?'" He said, "Then honoring the parents." He said, "I said, 'Then what?'" He said, "Then Jihad in the way of Allah." And had I asked him for more, he would have increased me.
