The word(s) "reminder" appears 39 time(s) in 39 verse(s) in Quran in Saheeh International translation.

(1) Those who spend their wealth in the way of Allah and then do not follow up what they have spent with reminders [of it] or [other] injury will have their reward with their Lord, and there will be no fear concerning them, nor will they grieve.

(2) O you who have believed, do not invalidate your charities with reminders or injury as does one who spends his wealth [only] to be seen by the people and does not believe in Allah and the Last Day. His example is like that of a [large] smooth stone upon which is dust and is hit by a downpour that leaves it bare. They are unable [to keep] anything of what they have earned. And Allah does not guide the disbelieving people.

(3) And when you see those who engage in [offensive] discourse concerning Our verses, then turn away from them until they enter into another conversation. And if Satan should cause you to forget, then do not remain after the reminder with the wrongdoing people.

(4) And those who fear Allah are not held accountable for the disbelievers at all, but [only for] a reminder - that perhaps they will fear Him.

(5) Those are the ones whom Allah has guided, so from their guidance take an example. Say, "I ask of you for this message no payment. It is not but a reminder for the worlds."

(6) [This is] a Book revealed to you, [O Muhammad] - so let there not be in your breast distress therefrom - that you may warn thereby and as a reminder to the believers.

(7) Then do you wonder that there has come to you a reminder from your Lord through a man from among you, that he may warn you and that you may fear Allah so you might receive mercy."

(8) Then do you wonder that there has come to you a reminder from your Lord through a man from among you, that he may warn you? And remember when He made you successors after the people of Noah and increased you in stature extensively. So remember the favors of Allah that you might succeed.

(9) And establish prayer at the two ends of the day and at the approach of the night. Indeed, good deeds do away with misdeeds. That is a reminder for those who remember.

(10) And each [story] We relate to you from the news of the messengers is that by which We make firm your heart. And there has come to you, in this, the truth and an instruction and a reminder for the believers.
