The answer
Yes, El-Hawarion are the Disciples of Our Lord Jesus Christ, who were called and chosen by Him, and who conversed with Him for the duration of His ministry on Earth. After His ascension, they went out preaching, according to the commission that was given them by Christ when He said, “Go ye into all the world, and preach the Gospel to every creature. He that believeth and is baptised shall be saved; but he that believeth not shall be damned” (Mark 16:15-16).
They were called "El-Hawarion", due to the purity and goodness of their hearts and disposition. The word hawārey means counsellor; guide; one with a pure heart. Given that the Disciples of Christ were adorned with such traits, they were referred to as "El-Hawarion".
