Fasting belongs to the religion of Abraham
The Quran presents Submission as the religion of Abraham, and Muhammad is commanded to follow Abraham's way. The core religious practices, including the Contact Prayers, Zakat, fasting, and Hajj, are preserved through Abraham rather than introduced later.
The Quran confirms this regarding fasting. It connects believers to those who came before them.
“O you who believe, fasting is decreed for you, as it was decreed for those before you, that you may attain salvation.”
Ramadan commemorates the revelation of the Quran and reinforces the monotheistic legacy of Abraham. The believers fast during this month to observe what God decreed and to grow in restraint, gratitude, and obedience.
