The word(s) "admonish" appears 3 time(s) in 3 verse(s) in Quran in Saheeh International translation.

(1) Those are the ones of whom Allah knows what is in their hearts, so turn away from them but admonish them and speak to them a far-reaching word.

(2) Indeed, Allah orders justice and good conduct and giving to relatives and forbids immorality and bad conduct and oppression. He admonishes you that perhaps you will be reminded.

(3) And those who pronounce thihar from their wives and then [wish to] go back on what they said - then [there must be] the freeing of a slave before they touch one another. That is what you are admonished thereby; and Allah is Acquainted with what you do.
