Is it permissible to name a son (Abdullah ibn 'Umar) and address him as "O Ibn 'Umar"?

Question:
May Allah reward you, Honorable Shaykh. This questioner says: I was blessed with a son and I named him after the noble Companion Abdullah ibn 'Umar (may Allah be pleased with them both), because I love him for his status in the Sunnah. Sometimes I call this son of mine by saying "Ibn 'Umar" to him instead of Abdullah. Is this action correct?

Answer:
Call them by their fathers' names. Allah the Exalted says: Call them by their fathers' names. Call him by his father's name and do not attribute him to 'Umar. As for you naming him 'Abdullah, there is no objection to that. But if you say "Ibn 'Umar" while you are not a descendant of 'Umar, attributing him to 'Umar ibn al-Khattab, that is not permissible. Yes.
