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

(61) They said: "Shall we believe in two men like ourselves? And their people are subject to us!"

(62) And Allah has created every animal from water: of them there are some that creep on their bellies; some that walk on two legs; and some that walk on four. Allah creates what He wills for verily Allah has power over all things.

(63) It is He Who has let free the two bodies of flowing water: One palatable and sweet, and the other salt and bitter; yet has He made a barrier between them, a partition that is forbidden to be passed.

(64) And when the two bodies saw each other, the people of Moses said: "We are sure to be overtaken."

(65) We sent (aforetime), to the Thamud, their brother Salih, saying, "Serve Allah": But behold, they became two factions quarrelling with each other.

(66) Or, Who has made the earth firm to live in; made rivers in its midst; set thereon mountains immovable; and made a separating bar between the two bodies of flowing water? (can there be another) god besides Allah? Nay, most of them know not.

(67) And he entered the city at a time when its people were not watching: and he found there two men fighting,- one of his own religion, and the other, of his foes. Now the man of his own religion appealed to him against his foe, and Moses struck him with his fist and made an end of him. He said: "This is a work of Evil (Satan): for he is an enemy that manifestly misleads!"

(68) And when he arrived at the watering (place) in Madyan, he found there a group of men watering (their flocks), and besides them he found two women who were keeping back (their flocks). He said: "What is the matter with you?" They said: "We cannot water (our flocks) until the shepherds take back (their flocks): And our father is a very old man."

(69) He said: "Be that (the agreement) between me and thee: whichever of the two terms I fulfil, let there be no ill-will to me. Be Allah a witness to what we say."

(70) "Move thy hand into thy bosom, and it will come forth white without stain (or harm), and draw thy hand close to thy side (to guard) against fear. Those are the two credentials from thy Lord to Pharaoh and his Chiefs: for truly they are a people rebellious and wicked."
