The word(s) "lo" appears 3454 time(s) in 2453 verse(s) in Quran in Muhammad Pickthal translation.

(841) Thus have We revealed it, a decisive utterance in Arabic; and if thou shouldst follow their desires after that which hath come unto thee of knowledge, then truly wouldst thou have from Allah no protecting friend nor defender.

(842) Those who were before them plotted; but all plotting is Allah's. He knoweth that which each soul earneth. The disbelievers will come to know for whom will be the sequel of the (heavenly) Home.

(843) Alif. Lam. Ra. (This is) a Scripture which We have revealed unto thee (Muhammad) that thereby thou mayst bring forth mankind from darkness unto light, by the permission of their lord, unto the path of the Mighty, the Owner of Praise,

(844) Allah, unto Whom belongeth whatsoever is in the heavens and whatsoever is in the earth. and woe unto the disbelievers from an awful doom;

(845) Those who love the life of the world more than the Hereafter, and debar (men) from the way of Allah and would have it crooked: such are far astray.

(846) We verily sent Moses with Our revelations, saying: Bring thy people forth from darkness unto light. And remind them of the days of Allah. lo! therein are revelations for each steadfast, thankful (heart).

(847) And (remind them) how Moses said unto his people: Remember Allah's favour unto you when He delivered you from Pharaoh's folk who were afflicting you with dreadful torment, and were slaying your sons and sparing your women; that was a tremendous trial from your lord.

(848) And when your lord proclaimed: If ye give thanks, I will give you more; but if ye are thankless, lo! My punishment is dire.

(849) And Moses said: Though ye and all who are in the earth prove thankless, lo! Allah verily is Absolute, Owner of Praise.

(850) Hath not the history of those before you reached you: the folk of Noah, and (the tribes of) A'ad and Thamud, and those after them? None save Allah knoweth them. Their messengers came unto them with clear proofs, but they thrust their hands into their mouths, and said: lo! we disbelieve in that wherewith ye have been sent, and lo! we are in grave doubt concerning that to which ye call us.
