The word(s) "had" appears 368 time(s) in 323 verse(s) in Quran in Abdullah Yusuf Ali translation.

(41) For the iniquity of the Jews We made unlawful for them certain (foods) good and wholesome which had been lawful for them;- in that they hindered many from Allah's Way;-

(42) Remember Moses said to his people: "O my people! Call in remembrance the favour of Allah unto you, when He produced prophets among you, made you kings, and gave you what He had not given to any other among the peoples.

(43) (But) among (their) Allah-fearing men were two on whom Allah had bestowed His grace: They said: "Assault them at the (proper) Gate: when once ye are in, victory will be yours; But on Allah put your trust if ye have faith."

(44) As to those who reject Faith,- if they had everything on earth, and twice repeated, to give as ransom for the penalty of the Day of Judgment, it would never be accepted of them, theirs would be a grievous penalty.

(45) And in their footsteps We sent Jesus the son of Mary, confirming the Law that had come before him: We sent him the Gospel: therein was guidance and light, and confirmation of the Law that had come before him: a guidance and an admonition to those who fear Allah.

(46) To thee We sent the Scripture in truth, confirming the scripture that came before it, and guarding it in safety: so judge between them by what Allah hath revealed, and follow not their vain desires, diverging from the Truth that hath come to thee. To each among you have we prescribed a law and an open way. If Allah had so willed, He would have made you a single people, but (His plan is) to test you in what He hath given you: so strive as in a race in all virtues. The goal of you all is to Allah; it is He that will show you the truth of the matters in which ye dispute;

(47) If only the People of the Book had believed and been righteous, We should indeed have blotted out their iniquities and admitted them to gardens of bliss.

(48) If only they had stood fast by the Law, the Gospel, and all the revelation that was sent to them from their Lord, they would have enjoyed happiness from every side. There is from among them a party on the right course: but many of them follow a course that is evil.

(49) Christ the son of Mary was no more than a messenger; many were the messengers that passed away before him. His mother was a woman of truth. They had both to eat their (daily) food. See how Allah doth make His signs clear to them; yet see in what ways they are deluded away from the truth!

(50) If only they had believed in Allah, in the Prophet, and in what hath been revealed to him, never would they have taken them for friends and protectors, but most of them are rebellious wrong-doers.
