The word(s) "swift" appears 16 time(s) in 16 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) That Allah may requite each soul according to its deserts; and verily Allah is swift in calling to account.

(12) Until the Gog and Magog (people) are let through (their barrier), and they swiftly swarm from every hill.

(13) But the Unbelievers,- their deeds are like a mirage in sandy deserts, which the man parched with thirst mistakes for water; until when he comes up to it, he finds it to be nothing: But he finds Allah (ever) with him, and Allah will pay him his account: and Allah is swift in taking account.

(14) Behold, there were brought before him, at eventide coursers of the highest breeding, and swift of foot;

(15) That Day will every soul be requited for what it earned; no injustice will there be that Day, for Allah is swift in taking account.

(16) "As if there were (a string of) yellow camels (marching swiftly)."
