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

(801) Or a little more; and recite the Qur'an in slow, measured rhythmic tones.

(802) And leave Me (alone to deal with) those in possession of the good things of life, who (yet) deny the Truth; and bear with them for a little while.

(803) one Day the earth and the mountains will be in violent commotion. And the mountains will be as a heap of sand poured out and flowing down.

(804) Leave Me alone, (to deal) with the (creature) whom I created (bare and) alone!-

(805) Naught doth it permit to endure, and naught doth it leave alone!-

(806) And We have set none but angels as Guardians of the Fire; and We have fixed their number only as a trial for Unbelievers,- in order that the People of the Book may arrive at certainty, and the Believers may increase in Faith,- and that no doubts may be left for the People of the Book and the Believers, and that those in whose hearts is a disease and the Unbelievers may say, "What symbol doth Allah intend by this?"

(810) Does man think that We cannot assemble his bones?
