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

(1) Who believe in the Ghaib and perform As-Salat (Iqamat-as-Salat), and spend out of what We have provided for them [i.e. give Zakat , spend on themselves, their parents, their children, their wives, etc., and also give charity to the poor and also in Allah's Cause - Jihad].

(2) He said: "O Adam! Inform them of their names," and when he had informed them of their names, He said: "Did I not tell you that I know the Ghaib (Unseen) in the heavens and the earth, and I know what you reveal and what you have been concealing?"

(3) And We shaded you with clouds and sent down on you Al-Manna and the quails, (saying): "Eat of the good lawful things We have provided for you," (but they rebelled). And they did not wrong Us but they wronged themselves.

(4) But those who did wrong changed the word from that which had been told to them for another, so We sent upon the wrong-doers Rijz (a punishment) from the heaven because of their rebelling against Allah's obedience. (Tafsir At-Tabari).

(5) Then after that you turned away. had it not been for the Grace and Mercy of Allah upon you, indeed you would have been among the losers.

(6) And when there came to them (the Jews), a Book (this Qur'an) from Allah confirming what is with them [the Taurat (Torah) and the Injeel (Gospel)], although aforetime they had invoked Allah (for coming of Muhammad صلى الله عليه وسلم) in order to gain victory over those who disbelieved, then when there came to them that which they had recognised, they disbelieved in it. So let the Curse of Allah be on the disbelievers.

(7) They followed what the Shayatin (devils) gave out (falsely of the magic) in the lifetime of Sulaiman (Solomon). Sulaiman did not disbelieve, but the Shayatin (devils) disbelieved, teaching men magic and such things that came down at Babylon to the two angels, Harut and Marut, but neither of these two (angels) taught anyone (such things) till they had said, "We are only for trial, so disbelieve not (by learning this magic from us)." And from these (angels) people learn that by which they cause separation between man and his wife, but they could not thus harm anyone except by Allah's Leave. And they learn that which harms them and profits them not. And indeed they knew that the buyers of it (magic) would have no share in the Hereafter. And how bad indeed was that for which they sold their ownselves, if they but knew.

(8) And if they had believed, and guarded themselves from evil and kept their duty to Allah, far better would have been the reward from their Lord, if they but knew!

(9) And those who followed will say: "If only we had one more chance to return (to the worldly life), we would disown (declare ourselves as innocent from) them as they have disowned (declared themselves as innocent from) us." Thus Allah will show them their deeds as regrets for them. And they will never get out of the Fire.

(10) And fight in the Way of Allah those who fight you, but transgress not the limits. Truly, Allah likes not the transgressors. [This Verse is the first one that was revealed in connection with Jihad, but it was supplemented by another (9:36)].
