The word(s) "one" appears 1001 time(s) in 857 verse(s) in Quran in Abdullah Yusuf Ali translation.

(1) Of a surety, they are the ones who make mischief, but they realise (it) not.

(2) When they meet those who believe, they say: "We believe;" but when they are alone with their evil ones, they say: "We are really with you: We (were) only jesting."

(3) Allah will throw back their mockery on them, and give them rope in their trespasses; so they will wander like blind ones (To and fro).

(4) Or (another similitude) is that of a rain-laden cloud from the sky: In it are zones of darkness, and thunder and lightning: They press their fingers in their ears to keep out the stunning thunder-clap, the while they are in terror of death. But Allah is ever round the rejecters of Faith!

(5) But if ye cannot- and of a surety ye cannot- then fear the Fire whose fuel is men and stones,- which is prepared for those who reject Faith.

(6) Behold, thy Lord said to the angels: "I will create a vicegerent on earth." They said: "Wilt Thou place therein one who will make mischief therein and shed blood?- whilst we do celebrate Thy praises and glorify Thy holy (name)?" He said: "I know what ye know not."

(7) They said: "Glory to Thee, of knowledge We have none, save what Thou Hast taught us: In truth it is Thou Who art perfect in knowledge and wisdom."

(8) O Children of Israel! call to mind the (special) favour which I bestowed upon you, and fulfil your covenant with Me as I fulfil My Covenant with you, and fear none but Me.

(9) And believe in what I reveal, confirming the revelation which is with you, and be not the first to reject Faith therein, nor sell My Signs for a small price; and fear Me, and Me alone.

(10) Then guard yourselves against a day when one soul shall not avail another nor shall intercession be accepted for her, nor shall compensation be taken from her, nor shall anyone be helped (from outside).
