What is the wisdom behind the legislation of fasting?

Among the wisdoms of fasting are:

1. It is a means of showing gratitude for blessings.

2. It is a means of abandoning forbidden acts.

3. Overcoming lust, as stated in the Prophetic Hadeeth: "O young people, whoever among you can afford to marry, let him do so, for it is more lowering of the gaze and more protective of the private parts. And whoever cannot afford it, let him fast, for it will be a shield for him."

4. It necessitates mercy and compassion towards the poor.

5. It involves overcoming and weakening Satan, because "Satan flows through the son of Adam like blood," and fasting constricts his passages.

6. Training the soul in the consciousness of Allah the Almighty.

7. Detachment from this world and its desires, and inclination towards what is with Allah.

8. Accustoming the believer to increase in acts of obedience.
