Why is Ramadan blessed?
In fact, this is a delicate question. Allah, Exalted and Sublime be He, casts tranquility into the heart of the believer. In other words, when the believer performs a good deed seeking Allah's Pleasure, he will be rewarded by Allah the Almighty through casting tranquility, stability, happiness and balance into his heart.
In my opinion, the greatest Divine Bestowal the Sa'em (the person who observes fasting) has in Ramadan is his ability to obey Allah the Almighty after he ignores his desires. He leaves cold water even though the weather is hot. He abstains from satisfying his body’s desires and needs while fasting, seeking Allah's pleasure. As a result, he feels that he is doing a great work and that Allah loves him. This feeling is confirmed by being connected to Allah, Exalted and Sublime be He.
