The word(s) "wouldst" appears 23 time(s) in 21 verse(s) in Quran in Abdullah Yusuf Ali translation.

(11) Thou wouldst have seen the sun, when it rose, declining to the right from their Cave, and when it set, turning away from them to the left, while they lay in the open space in the midst of the Cave. Such are among the Signs of Allah: He whom Allah, guides is rightly guided; but he whom Allah leaves to stray,- for him wilt thou find no protector to lead him to the Right Way.

(12) Thou wouldst have deemed them awake, whilst they were asleep, and We turned them on their right and on their left sides: their dog stretching forth his two fore-legs on the threshold: if thou hadst come up on to them, thou wouldst have certainly turned back from them in flight, and wouldst certainly have been filled with terror of them.

(13) The other said: "If then thou wouldst follow me, ask me no questions about anything until I myself speak to thee concerning it."

(14) (Moses) said: "If ever I ask thee about anything after this, keep me not in thy company: then wouldst thou have received (full) excuse from my side."

(15) They swear their strongest oaths by Allah that, if only thou wouldst command them, they would leave (their homes). Say: "Swear ye not; Obedience is (more) reasonable; verily, Allah is well acquainted with all that ye do."

(16) Is, then, one against whom the decree of Punishment is justly due (equal to one who eschews Evil)? wouldst thou, then, deliver one (who is) in the Fire?

(17) They will not fight you (even) together, except in fortified townships, or from behind walls. Strong is their fighting (spirit) amongst themselves: thou wouldst think they were united, but their hearts are divided: that is because they are a people devoid of wisdom.

(18) Had We sent down this Qur'an on a mountain, verily, thou wouldst have seen it humble itself and cleave asunder for fear of Allah. Such are the similitudes which We propound to men, that they may reflect.

(19) And when it is said to them, "Come, the Messenger of Allah will pray for your forgiveness", they turn aside their heads, and thou wouldst see them turning away their faces in arrogance.

(20) And round about them will (serve) youths of perpetual (freshness): If thou seest them, thou wouldst think them scattered Pearls.
