“The sword is the key of heaven and hell; a drop of blood shed in the cause of Allah, a night spent in arms, is of more avail than two months of fasting or prayer: whosoever falls in battle, his sins are forgiven, and at the day of judgment his limbs shall be supplied by the wings of angels and cherubim.”
