The word(s) "admonition" appears 39 time(s) in 38 verse(s) in Quran in Mohsin Khan translation.

(1) And when you have divorced women and they have fulfilled the term of their prescribed period, do not prevent them from marrying their (former) husbands, if they mutually agree on reasonable basis. This (instruction) is an admonition for him among you who believes in Allah and the Last Day. That is more virtuous and purer for you. Allah knows and you know not.

(2) He grants Hikmah to whom He pleases, and he, to whom Hikmah is granted, is indeed granted abundant good. But none remember (will receive admonition) except men of understanding.

(3) Those who eat Riba (usury) will not stand (on the Day of Resurrection) except like the standing of a person beaten by Shaitan (Satan) leading him to insanity. That is because they say: "Trading is only like Riba (usury)," whereas Allah has permitted trading and forbidden Riba (usury). So whosoever receives an admonition from his Lord and stops eating Riba (usury) shall not be punished for the past; his case is for Allah (to judge); but whoever returns [to Riba (usury)], such are the dwellers of the Fire - they will abide therein.

(4) It is He Who has sent down to you (Muhammad صلى الله عليه وسلم) the Book (this Qur'an). In it are Verses that are entirely clear, they are the foundations of the Book [and those are the Verses of Al-Ahkam (commandments), Al-Fara'id (obligatory duties) and Al-Hudud (legal laws for the punishment of thieves, adulterers)]; and others not entirely clear. So as for those in whose hearts there is a deviation (from the truth) they follow that which is not entirely clear thereof, seeking Al-Fitnah (polytheism and trials), and seeking for its hidden meanings, but none knows its hidden meanings save Allah. And those who are firmly grounded in knowledge say: "We believe in it; the whole of it (clear and unclear Verses) are from our Lord." And none receive admonition except men of understanding. (Tafsir At-Tabari).

(5) And in their footsteps, We sent 'Îsa (Jesus), son of Maryam (Mary), confirming the Taurat (Torah) that had come before him, and We gave him the Injeel (Gospel), in which was guidance and light and confirmation of the Taurat (Torah) that had come before it, a guidance and an admonition for Al-Muttaqun (the pious - See V.2:2).

(6) "Never did I say to them aught except what You (Allah) did command me to say: 'Worship Allah, my Lord and your Lord.' And I was a witness over them while I dwelt amongst them, but when You took me up, You were the Watcher over them; and You are a Witness to all things. (This is a great admonition and warning to the Christians of the whole world).

(7) And all that We relate to you (O Muhammad صلى الله عليه و سلم) of the news of the Messengers is in order that We may make strong and firm your heart thereby. And in this (chapter of the Qur'an) has come to you the truth, as well as an admonition and a reminder for the believers.

(8) "And speak to him mildly, perhaps he may accept admonition or fear (Allah)."

(9) Comes not unto them an admonition (a chapter of the Qur'an) from their Lord as a recent revelation but they listen to it while they play

(10) And indeed We have sent down for you Ayat (proofs, evidence, verses, lessons, signs, revelations, etc.) that make things plain, and the example of those who passed away before you, and an admonition for those who are Al-Muttaqun (the pious - See V.2:2).
