The Almighty God explains the purpose of fasting in verse 183 of Chapter Baqarah as follows:
“Oh, you who believe! Fasting has been prescribed for you in the way that was prescribed for the ones before you, so that you may protect yourselves.” (2:183)
Fasting people abstain from eating, drinking and sexual intercourse only to obey the command of God and to gain His approval. This increases their motivation for protecting themselves against probable sins.
Fasting also maintains a person’s health, teaches patience, discipline and the value of God’s blessings as it lets the person know what it is like to be hungry.
