From the Benefits of Fasting

Allah (Subhaanahu wa Ta'aala) says:

 “O you who believe, fasting has been prescribed for you as it was prescribed for those before you so that you may attain taqwa.” [Soorah al-Baqarah, Ayah 183]

The Messenger of Allah (sal-Allahu 'alayhe wa sallam) said:

“Fasting is protection, i.e. protection from the Fire of Hell.” [The authenticity of this narration has been agreed upon by al-Bukhaaree and Muslim]

And he (sal-Allahu 'alayhe wa sallam) said:

“Whoever fasts Ramadan with Iman while believing in its obligation and being hopeful for the reward, all that has preceded of his sins shall be forgiven.” [The authenticity of this narration has been agreed upon by al-Bukhaaree and Muslim]

Know! O Muslim Brother, that Allah has prescribed fasting, and it is an act of worship which has many benefits, amongst them:

a) Fasting allows the body's digestive system and the stomach to rest allowing the body to recuperate and strengthen. This is beneficial for many ailments. Likewise, fasting allows the smoker to take a break from smoking and in doing so assists him in abandoning it.

b) Fasting is a purification of the soul, and accustomising it upon good, worship, patience and sincerity.
