Zakat 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 invented later.
Zakat is not a later institutional tax or a cultural donation custom. It is one of the foundational practices of Submission: a recurring act of obedience through which the believer gives from what God has provided.
The Quran connects the righteous community with those who establish the Contact Prayers and give Zakat. Abraham and his descendants were commanded in worship, righteousness, and charitable obligation.
