Musnad Ahmad 1018:65

'Affan narrated to us, Shu'bah narrated to us, he said: 'Asim ibn Kulayb informed me, he said: I heard 'Iyad ibn Murthid, or Murthid ibn 'Iyad, from a man among them, that he asked the Prophet, peace and blessings of Allah be upon him, about a deed that would cause him to enter Paradise. He mentioned it, except that he said: "Their equipment suffices them when they are present, and you carry it to them when they are absent."
