The word(s) "two" appears 126 time(s) in 106 verse(s) in Quran in Abdullah Yusuf Ali translation.

(81) When We (first) sent to them two messengers, they rejected them: But We strengthened them with a third: they said, "Truly, we have been sent on a mission to you."

(82) For they were two of our believing Servants.

(83) When they entered the presence of David, and he was terrified of them, they said: "Fear not: we are two disputants, one of whom has wronged the other: Decide now between us with truth, and treat us not with injustice, but guide us to the even Path..

(84) Allah puts forth a Parable a man belonging to many partners at variance with each other, and a man belonging entirely to one master: are those two equal in comparison? Praise be to Allah! but most of them have no knowledge.

(85) Say: Is it that ye deny Him Who created the earth in two Days? And do ye join equals with Him? He is the Lord of (all) the Worlds.

(86) So He completed them as seven firmaments in two Days, and He assigned to each heaven its duty and command. And We adorned the lower heaven with lights, and (provided it) with guard. Such is the Decree of (Him) the Exalted in Might, Full of Knowledge.

(87) Also, they say: "Why is not this Qur'an sent down to some leading man in either of the two (chief) cities?"

(88) But (there is one) who says to his parents, "Fie on you! Do ye hold out the promise to me that I shall be raised up, even though generations have passed before me (without rising again)?" And they two seek Allah's aid, (and rebuke the son): "Woe to thee! Have faith! for the promise of Allah is true." But he says, "This is nothing but tales of the ancients!"

(89) If two parties among the Believers fall into a quarrel, make ye peace between them: but if one of them transgresses beyond bounds against the other, then fight ye (all) against the one that transgresses until it complies with the command of Allah; but if it complies, then make peace between them with justice, and be fair: for Allah loves those who are fair (and just).

(90) The Believers are but a single Brotherhood: So make peace and reconciliation between your two (contending) brothers; and fear Allah, that ye may receive Mercy.
