Al-Muhaymin
The Guardian

Unto thee O Prophet have We vouchsafed this divine writ, setting forth the truth, confirming the truth of whatever there still remains of earlier revelations and determining what is true therein.
Judge, then, between the followers of earlier revelation in accordance with what God has
bestowed from on high, and do not follow their
errant views, forsaking the truth that has come
unto thee.
Al-Ma'idah 5:48, tr. Asad
