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

(1521) And among them are some who listen to you (O Muhammad صلى الله عليه وسلم) till when they go out from you, they say to those who have received knowledge: "What has he said just now? Such are men whose hearts Allah has sealed, and they follow their lusts (evil desires).

(1522) Those who believe say: "Why is not a Surah (chapter of the Qur'an) sent down (for us)? But when a decisive Surah (explaining and ordering things) is sent down, and fighting (Jihad - holy fighting in Allah's cause) is mentioned (i.e. ordained) therein, you will see those in whose hearts is a disease (of hypocrisy) looking at you with a look of one fainting to death. But it was better for them (hypocrites, to listen to Allah and to obey Him).

(1523) Do they not then think deeply in the Qur'an, or are their hearts locked up (from understanding it)?

(1524) Verily, those who have turned back (have apostatised) as disbelievers after the guidance has been manifested to them - Shaitan (Satan) has beautified for them (their false hopes), and (Allah) prolonged their term (age).

(1525) That is because they followed that which angered Allah and hated that which pleased Him. So He made their deeds fruitless.

(1526) He it is Who sent down As-Sakinah (calmness and tranquillity) into the hearts of the believers, that they may grow more in Faith along with their (present) Faith. And to Allah belong the hosts of the heavens and the earth, and Allah is Ever All-Knower, All-Wise.

(1527) That He may admit the believing men and the believing women to Gardens under which rivers flow (i.e. Paradise), to abide therein forever, and He may expiate from them their sins; and that is with Allah a supreme success,

(1528) And to Allah belong the hosts of the heavens and the earth. And Allah is Ever All-Powerful, All-Wise.

(1529) In order that you (O mankind) may believe in Allah and His Messenger (صلى الله عليه وسلم), and that you assist and honour him (صلى الله عليه وسلم), and (that you) glorify (Allah's) praises morning and afternoon.

(1530) And to Allah belongs the sovereignty of the heavens and the earth. He forgives whom He wills, and punishes whom He wills. And Allah is Ever Oft-Forgiving, Most Merciful.
