The word(s) "didst" appears 36 time(s) in 29 verse(s) in Quran in Abdullah Yusuf Ali translation.

(21) (Aaron) replied: "O son of my mother! Seize (me) not by my beard nor by (the hair of) my head! Truly I feared lest thou shouldst say, 'Thou has caused a division among the children of Israel, and thou didst not respect my word!'"

(22) (Allah) will say: "Thus didst Thou, when Our Signs came unto thee, disregard them: so wilt thou, this day, be disregarded."

(23) They will say: "Glory to Thee! not meet was it for us that we should take for protectors others besides Thee: But Thou didst bestow, on them and their fathers, good things (in life), until they forgot the Message: for they were a people (worthless and) lost."

(24) (Pharaoh) said: "Did we not cherish thee as a child among us, and didst thou not stay in our midst many years of thy life?

(25) "And thou didst a deed of thine which (thou knowest) thou didst, and thou art an ungrateful (wretch)!"

(26) If (We had) not (sent thee to the Quraish),- in case a calamity should seize them for (the deeds) that their hands have sent forth, they might say: "Our Lord! why didst Thou not sent us a messenger? We should then have followed Thy Signs and been amongst those who believe!"

(27) Behold! Thou didst say to one who had received the grace of Allah and thy favour: "Retain thou (in wedlock) thy wife, and fear Allah." But thou didst hide in thy heart that which Allah was about to make manifest: thou didst fear the people, but it is more fitting that thou shouldst fear Allah. Then when Zaid had dissolved (his marriage) with her, with the necessary (formality), We joined her in marriage to thee: in order that (in future) there may be no difficulty to the Believers in (the matter of) marriage with the wives of their adopted sons, when the latter have dissolved with the necessary (formality) (their marriage) with them. And Allah's command must be fulfilled.

(28) "(The reply will be:) 'Nay, but there came to thee my Signs, and thou didst reject them: thou wast Haughty, and became one of those who reject faith!'"

(29) and spend something (in charity) out of the substance which We have bestowed on you, before Death should come to any of you and he should say, "O my Lord! why didst Thou not give me respite for a little while? I should then have given (largely) in charity, and I should have been one of the doers of good".
