The word(s) "one" appears 806 time(s) in 722 verse(s) in Quran in Muhammad Habib Shakir translation.

(281) Your Allah is one Allah; so (as for) those who do not believe in the hereafter, their hearts are ignorant and they are proud.

(282) And Allah has said: Take not two gods, He is only one Allah; so of Me alone should you be afraid.

(283) And they set apart for what they do not know a portion of what We have given them. By Allah, you shall most certainly be questioned about that which you forged.

(284) And when a daughter is announced to one of them his face becomes black and he is full of wrath.

(285) Allah sets forth a parable: (consider) a slave, the property of another, (who) has no power over anything, and one whom We have granted from Ourselves a goodly sustenance so he spends from it secretly and openly; are the two alike? (All) praise is due to Allah! Nay, most of them do not know.

(286) And Allah sets forth a parable of two men; one of them is dumb, not able to do anything, and he is a burden to his master; wherever he sends him, he brings no good; can he be held equal with him who enjoins what is just, and he (himself) is on the right path?

(287) Do they not see the birds, constrained in the middle of the sky? None withholds them but Allah; most surely there are signs in this for a people who believe.

(288) And be not like her who unravels her yarn, disintegrating it into pieces after she has spun it strongly. You make your oaths to be means of deceit between you because (one) nation is more numerous than (another) nation. Allah only tries you by this; and He will most certainly make clear to you on the resurrection day that about which you differed.

(289) And if Allah please He would certainly make you a single nation, but He causes to err whom He pleases and guides whom He pleases; and most certainly you will be questioned as to what you did.

(290) And when We change (one) communication for (another) communication, and Allah knows best what He reveals, they say: You are only a forger. Nay, most of them do not know.
