Note 160 — ALL THE WARS OF MOHAMMAD WERE DEFENSIVE.
Reading edition
"The support of the Medina adherents, and the suspicion of an intended emigration, irritated the Koreish to severity; and this severity forced the Moslems to petition Mahomet for leave to emigrate. The two causes might co-exist and re-act one another; the persecution would hasten the departure of the converts, while each fresh departure would irritate the Koreish to greater cruelty."—William Muir's Life of Mahomet, Vol. II, pp. 242, 243, foot-note.
