The word(s) "so" appears 2327 time(s) in 1778 verse(s) in Quran in Mohsin Khan translation.

(31) 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.

(32) How bad is that for which they have sold their ownselves, that they should disbelieve in that which Allah has revealed (the Qur'an), grudging that Allah should reveal of His Grace unto whom He wills of His slaves. so they have drawn on themselves wrath upon wrath. And for the disbelievers, there is disgracing torment.

(33) And (remember) when We took your covenant and We raised above you the Mount (saying), "Hold firmly to what We have given you and hear (Our Word)." They said, "We have heard and disobeyed." And their hearts absorbed (the worship of) the calf because of their disbelief. Say: "Worst indeed is that which your faith enjoins on you if you are believers."

(34) Is it not (the case) that every time they make a covenant, some party among them throw it aside? Nay! (the truth is:) most of them believe not.

(35) 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.

(36) And to Allah belong the east and the west, so wherever you turn (yourselves or your faces) there is the Face of Allah (and He is High above, over His Throne). Surely! Allah is All-Sufficient for His creatures' needs, All-Knowing.

(37) And they (Jews, Christians and pagans) say: Allah has begotten a son (children or offspring) . Glory be to Him (Exalted be He above all that they associate with Him). Nay, to Him belongs all that is in the heavens and on earth, and all surrender with obedience (in worship) to Him.

(38) And those who have no knowledge say: "Why does not Allah speak to us (face to face) or why does not a sign come to us?" so said the people before them words of similar import. Their hearts are alike, We have indeed made plain the signs for people who believe with certainty.

(39) Those (who embraced Islam from Bani Israel) to whom We gave the Book [the Taurat (Torah)] [or those (Muhammad's صلى الله عليه وسلم companions) to whom We have given the Book (the Qur'an)] recite it (i.e. obey its orders and follow its teachings) as it should be recited (i.e. followed), they are the ones who believe therein. And whoso disbelieve in it (the Qur'an), those are they who are the losers. (Tafsir Al-Qurtubi).

(40) And fear the Day (of Judgement) when no person shall avail another, nor shall compensation be accepted from him, nor shall intercession be of use to him, nor shall they be helped.
