A promise is a commitment by someone to do or not to do something.
If you make a promise. So please do it all and it is haraam to break them and act in a treacherous manner. And when promises are not fulfilled, then man is proved to be a liar. Which leads to misunderstanding. And that it what increases the distance between people and love and respect are goes away.
As children, we grow up learning about keeping promises from our parents, teachers and the children’s books with their moral stories that mold our instincts to believe breaking a promise is morally wrong.

The Quran has praised those who keep their promises.
Fulfilling promises is one of the attributes of the pious according to the Book of ALLAH, and it one of the greatest means of attaining taqwa (piety, consciousness of ALLAH).

Failing to keep the promise falls into the category of lies and falsehood is a sign of hypocrisy. The Prophet Muhammad(ﷺ) has mentioned several hadiths regarding the promise vacancy.
It was narrated that Abdullah ibn Amr()said: The Messenger of Allah Prophet Muhammad(ﷺ) said: “There are four characteristics, whoever has them all is a pure hypocrite: when he speaks he lies, when he makes a promise he breaks it, when he makes a covenant he betrays it, and when he disputes he resorts to obscene speech. Whoever has one of them has one of the characteristics of hypocrisy, until he gives it up.”
(Al-Bukhari: 3178, Muslim: 58)

Learn to obey promises and make promises to someone when you are confident that you can fulfil your promise.
Please be sincere in your promises. I’m not just talking about the promises of love. Be sincere with your friends and relatives. And also in business matters. Likewise, improve your world and your life in the Hereafter.

Our Lord, give us in this world(that which is) good and in the Hereafter(that which is) good and protect us from the punishment of the fire. Ameen
Jazak ALLAH.🧚♀️
