The word(s) "stratagem" appears 5 time(s) in 5 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) If any do turn his back to them on such a day - unless it be in a stratagem of war, or to retreat to a troop (of his own)- he draws on himself the wrath of Allah, and his abode is Hell,- an evil refuge (indeed)!

(2) That, and also because Allah is He Who makes feeble the plans and stratagem of the Unbelievers.

(3) But when the forbidden months are past, then fight and slay the Pagans wherever ye find them, an seize them, beleaguer them, and lie in wait for them in every stratagem (of war); but if they repent, and establish regular prayers and practise regular charity, then open the way for them: for Allah is Oft-forgiving, Most Merciful.

(4) Then they sought a stratagem against him: but We made them the ones that lost most!

(5) (This failing), they then sought a stratagem against him, but We made them the ones most humiliated!
