Mishkat al-Masabih #3686

Abu Umama said: We went out with God’s Messenger on an expedition and when a man came upon a cave containing some water and vegetables he felt inclined to stay in it and withdraw from the world, so he asked God’s Messenger’s permission regarding that, but he replied, “I was not commissioned with Judaism, or Christianity, but with the easy Hanif religion. By Him in whose hand Muhammad's soul is, a morning or an evening expedition in God’s path is better than the world and what it contains, and for one of you to remain in the line of battle is better than his prayers for sixty years.” Ahmad transmitted it.
