The word(s) "cavalry" appears 2 time(s) in 2 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) "Lead to destruction those whom thou canst among them, with thy (seductive) voice; make assaults on them with thy cavalry and thy infantry; mutually share with them wealth and children; and make promises to them." But Satan promises them nothing but deceit.

(2) What Allah has bestowed on His Messenger (and taken away) from them - for this ye made no expedition with either cavalry or camelry: but Allah gives power to His messengers over any He pleases: and Allah has power over all things.
