The word(s) "had" appears 322 time(s) in 279 verse(s) in Quran in Muhammad Habib Shakir translation.

(61) And if We had made him angel, We would certainly have made him a man, and We would certainly have made confused to them what they make confused.

(62) And if their turning away is hard on you, then if you can seek an opening (to go down) into the earth or a ladder (to ascend up) to heaven so that you should bring them a sign and if Allah had pleased He would certainly have gathered them all on guidance, therefore be not of the ignorant.

(63) But when they neglected that with which they had been admonished, We opened for them the doors of all things, until when they rejoiced in what they were given We seized them suddenly; then lo! they were in utter despair.

(64) So when the night over-shadowed him, he saw a star; said he: Is this my Lord? So when it set, he said: I do not love the setting ones.

(65) Then when he saw the moon rising, he said: Is this my Lord? So when it set, he said: If my Lord had not guided me I should certainly be of the erring people.

(66) This is Allah's guidance, He guides thereby whom He pleases of His servants; and if they had set up others (with Him), certainly what they did would have become ineffectual for them.

(67) And who is more unjust than he who forges a lie against Allah, or says: It has been revealed to me; while nothing has been revealed to him, and he who says: I can reveal the like of what Allah has revealed? and if you had seen when the unjust shall be in the agonies of death and the angels shall spread forth their hands: Give up your souls; today shall you be recompensed with an ignominious chastisement because you spoke against Allah other than the truth and (because) you showed pride against His communications.

(68) And if Allah had pleased, they would not have set up others (with Him) and We have not appointed you a keeper over them, and you are not placed in charge of them.

(69) And even if We had sent down to them the angels and the dead had spoken to them and We had brought together all things before them, they would not believe unless Allah pleases, but most of them are ignorant.

(70) And thus did We make for every prophet an enemy, the Shaitans from among men and jinn, some of them suggesting to others varnished falsehood to deceive (them), and had your Lord pleased they would not have done it, therefore leave them and that which they forge.
