For centuries the concept of gratitude has always been associated with religion and moral philosophy, it was not until recently that this natural emotion aroused the interest of researchers, largely during the advent of positive psychology; this is a new branch of cognitive psychology that focuses on the positive aspects of the human psyche. Positive psychology aims to develop and nurture the affirmative aspects of human behavior, through scientific studies and effective intervention methods to achieve emotional satisfaction in individuals.

Accordingly, gratitude has been found to be one of the strongest positive emotions and is very often linked to happiness, the ultimate state of well-being that every human being strives to follow. Gratitude is an attitude where the individual shows himself to be grateful, even when they do not see what he has; this is an aspect of worship, expressing to God and others how they have benefited from our lives, showing them support, appreciation and benevolence “Because his blood has redeemed us, we are thankful”. Anyone who wants to define happiness almost always ends up with a single very common description: it is something that everyone wants to achieve, as they say “the purpose of life is to be happy”.

In this way, gratitude plays a very important role from the point of view of faith, which becomes an important quality for all existing religions, whether Judaism, Christianity and Islam. In this last religion, gratitude is totally fundamental and the being that is not grateful does not deserve the grace of God, where the study of the Koran perpetuates that idea within its followers since Muslim law establishes that before thanking anyone, one must thank to God, because this is the only way in which the omnipotent will be able to compensate all those pleasures that are requested of him. Among the different signs of gratitude in Islamic law is: praying five prayers every day to thank the kindness you have for your children and the practice of fasting during the period of the month of Ramadan, trying to symbolize your respect for God. .
