The word(s) "lo" appears 2523 time(s) in 1916 verse(s) in Quran in Mohsin Khan translation.

(1821) A reward from your lord, an ample calculated gift (according to the best of their good deeds),

(1822) (From) the lord of the heavens and the earth, and whatsoever is in between them, the Most Gracious, with Whom they cannot dare to speak (on the Day of Resurrection except by His Leave).

(1823) The Day that Ar-Ruh [Jibril (Gabriel) or another angel] and the angels will stand forth in rows, they will not speak except him whom the Most Gracious (Allah) allows, and he will speak what is right.

(1824) That is (without doubt) the True Day. So, whosoever wills, let him seek a place with (or a way to) His lord (by obeying Him in this worldly life)!

(1825) And by those that swim along (i.e. angels or planets in their orbits).

(1826) And by those angels who arrange to do the Commands of their lord, (so verily, you disbelievers will be called to account).

(1827) On the Day (when the first blowing of the Trumpet is blown), the earth and the mountains will shake violently (and everybody will die).

(1828) The second blowing of the Trumpet follows it (and everybody will be resurrected).

(1829) They say: "It would in that case, be a return with loss!"

(1830) But it will be only a single Zajrah [shout (i.e., the second blowing of the Trumpet)], (See Verse 37:19).
