The word(s) "had" appears 413 time(s) in 356 verse(s) in Quran in Mohsin Khan translation.

(51) The people of the Scripture (Jews) ask you to cause a book to descend upon them from heaven. Indeed they asked Musa (Moses) for even greater than that, when they said: "Show us Allah in public," but they were struck with thunderclap and lightning for their wickedness. Then they worshipped the calf even after clear proofs, evidence, and signs had come to them. (Even) so We forgave them. And We gave Musa (Moses) a clear proof of authority.

(52) For the wrong-doing of the Jews, We made unlawful for them certain good foods which had been lawful for them - and for their hindering many from Allah's Way;

(53) And (remember) when Musa (Moses) said to his people: "O my people! Remember the Favour of Allah to you when He made Prophets among you, made you kings and gave you what He had not given to any other among the 'Alamin (mankind and jinn, in the past)."

(54) Two men of those who feared (Allah and) on whom Allah had bestowed His Grace (they were يوشع وكالب Yusha' and Kalab) said: "Assault them through the gate; for when you are in, victory will be yours; and put your trust in Allah if you are believers indeed."

(55) Verily, those who disbelieve, if they had all that is in the earth, and as much again therewith to ransom themselves thereby from the torment on the Day of Resurrection, it would never be accepted of them, and theirs would be a painful torment.

(56) And in their footsteps, We sent 'Îsa (Jesus), son of Maryam (Mary), confirming the Taurat (Torah) that had come before him, and We gave him the Injeel (Gospel), in which was guidance and light and confirmation of the Taurat (Torah) that had come before it, a guidance and an admonition for Al-Muttaqun (the pious - See V.2:2).

(57) And We have sent down to you (O Muhammad صلى الله عليه وسلم) the Book (this Qur'an) in truth, confirming the Scripture that came before it and Muhaymin (trustworthy in highness and a witness) over it (old Scriptures) . So judge among them by what Allah has revealed, and follow not their vain desires, diverging away from the truth that has come to you. To each among you, We have prescribed a law and a clear way. If Allah had willed, He would have made you one nation, but that (He) may test you in what He has given you; so compete in good deeds. The return of you (all) is to Allah; then He will inform you about that in which you used to differ.

(58) And if only the people of the Scripture (Jews and Christians) had believed (in Muhammad صلى الله عليه وسلم) and warded off evil (sin, ascribing partners to Allah) and had become Al-Muttaqun (the pious - See V.2:2) We would indeed have expiated from them their sins and admitted them to Gardens of pleasure (in Paradise).

(59) And if only they had acted according to the Taurat (Torah), the Injeel (Gospel), and what has (now) been sent down to them from their Lord (the Qur'an), they would surely have gotten provision from above them and from underneath their feet. There are from among them people who are on the right course (i.e. they act on the revelation and believe in Prophet Muhammad صلى الله عليه وسلم as 'Abdullah bin Salam رضي الله عنه), but many of them do evil deeds.

(60) And had they believed in Allah, and in the Prophet (Muhammad صلى الله عليه وسلم) and in what has been revealed to him, never would they have taken them (the disbelievers) as Auliya' (protectors and helpers); but many of them are the Fasiqun (rebellious, disobedient to Allah).
