The word(s) "first" appears 63 time(s) in 59 verse(s) in Quran in Mohsin Khan translation.

(11) And truly you have come unto Us alone (without wealth, companions or anything else) as We created you the first time. You have left behind you all that which We had bestowed on you. We see not with you your intercessors whom you claimed to be partners with Allah. Now all relations between you and them have been cut off, and all that you used to claim has vanished from you.

(12) And We shall turn their hearts and their eyes away (from guidance), as they refused to believe therein for the first time, and We shall leave them in their trespass to wander blindly.

(13) "He has no partner. And of this I have been commanded, and I am the first of the Muslims."

(14) (Allah) will say: "Enter you in the company of nations who passed away before you, of men and jinn, into the Fire." Every time a new nation enters, it curses its sister nation (that went before) until they will be gathered all together in the Fire. The last of them will say to the first of them: "Our Lord! These misled us, so give them a double torment of the Fire." He will say: "For each one there is double (torment), but you know not."

(15) The first of them will say to the last of them: "You were not better than us, so taste the torment for what you used to earn."

(16) Await they just for the final fullfilment of the event? On the Day the event is finally fulfilled (i.e. the Day of Resurrection), those who neglected it before will say: "Verily, the Messengers of our Lord did come with the truth, now are there any intercessors for us that they might intercede on our behalf? Or could we be sent back (to the first life of the world) so that we might do (good) deeds other than those (evil) deeds which we used to do?" Verily, they have lost their ownselves (i.e. destroyed themselves) and that which they used to fabricate (invoking and worshipping others besides Allah) has gone away from them.

(17) They said: "O Musa (Moses)! Either you throw (first), or shall we have the (first) throw?"

(18) He [Musa (Moses)] said: "Throw you (first)." So when they threw, they bewitched the eyes of the people, and struck terror into them, and they displayed a great magic.

(19) And when Musa (Moses) came at the time and place appointed by Us, and his Lord (Allah) spoke to him; he said: "O my Lord! Show me (Yourself), that I may look upon You." Allah said: "You cannot see Me, but look upon the mountain; if it stands still in its place then you shall see Me." So when his Lord appeared to the mountain , He made it collapse to dust, and Musa (Moses) fell down unconscious. Then when he recovered his senses he said: "Glory be to You, I turn to You in repentance and I am the first of the believers."

(20) Will you not fight a people who have violated their oaths (pagans of Makkah), and intended to expel the Messenger while they did attack you first? Do you fear them? Allah has more right that you should fear Him if you are believers.
