Re: religion of prophet before Islam came
Ebionites have been called Nazarenes, (Nasara in Qur’an), or Essenes, all of these could be synonymous or could be three separate groups … No one really knows …
Waraka ibn Nawfal was Christian … Greek Orthodox are not older than the Ebionites … Ebionites are the legacy of Saint James … One of the inheritors of Jesus (AS) … There have a lineage that goes unbroken to Jesus (AS) … Whereas Trinitarian Christians all go back to Saul … who never even met Jesus (AS) …
Nonetheless they followed Christian/Jewish practice and they differed from the Hanif who didn’t have any coded practices … But a belief in Allah.
