The word(s) "preach" appears 21 time(s) in 19 verse(s) in Quran in Mohsin Khan translation.

(11) Say: "No reward do I ask of you for this (that which I have brought from my Lord and its preaching), save that whosoever wills may take a Path to his Lord.

(12) They said: "It is the same to us whether you preach or be not of those who preach.

(13) Verily, He Who has given you (O Muhammad صلى الله عليه وسلم) the Qur'an (i.e. ordered you to act on its laws and to preach it to others) will surely bring you back to Ma'ad (place of return, either to Makkah or to Paradise after your death). Say (O Muhammad صلى الله عليه وسلم): "My Lord is Aware of him who brings guidance, and of him who is in manifest error."

(14) And let them not turn you (O Muhammad صلى الله عليه وسلم) away from (preaching) the Ayat (revelations and verses) of Allah after they have been sent down to you: and invite (men) to (believe in) your Lord and be not of Al-Mushrikun (those who associate partners with Allah, e.g. polytheists, pagans, idolaters, and those who disbelieve in the Oneness of Allah and deny the Prophethood of Messenger Muhammad صلى الله عليه وسلم).

(15) And remind (by preaching the Qur'an, O Muhammad صلى الله عليه وسلم), for verily, the reminding profits the believers.

(16) Or is it that you (O Muhammad صلى الله عليه وسلم) ask a wage from them (for your preaching of Islamic Monotheism) so that they are burdened with a load of debt?

(17) Perfect wisdom (this Qur'an), but (the preaching of) warners benefit them not.

(18) Because there came to him the blind man (i.e. 'Abdullah bin Umm-Maktum, who came to the Prophet صلى الله عليه وسلم while he was preaching to one or some of the Quraish chiefs).

(19) Except those who believe (in Islamic Monotheism) and do righteous good deeds, and recommend one another to the truth [i.e. order one another to perform all kinds of good deeds (Al-Ma'ruf) which Allah has ordained, and abstain from all kinds of sins and evil deeds (Al-Munkar which Allah has forbidden], and recommend one another to patience (for the sufferings, harms, and injuries which one may encounter in Allah's Cause during preaching His religion of Islamic Monotheism or Jihad).
