15. “Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad ibn al-Hajjal from Tha’labah from Mu’ammar form abu Ja‘far (a.s.), who has said the following: “All goodness is in the sword, under the sword and under the shadow of the sword.” “I heard him saying, ‘Goodness, all of it, is tied to the forehead of the horses (and it remains so) up to the Day of Judgment (horses of the fighters for the cause of Allah).”’
