Qutbuddin
It means 'Pivot/Axis of the Religion,' referring to the spiritual pole in Sufi hierarchy who serves as the cosmic axis of the faith.
While not mentioned verbatim in the Quran, it derives from Quranic concepts of divine centrality and religious devotion, using the Arabic word Qutb.
He was a 13th-century Chishti Sufi saint of Delhi, spiritual successor to Moinuddin Chishti, known for extreme asceticism and miraculous spiritual states.
Yes, though rare, it carries strong scholarly and spiritual connotations suitable for families with Sufi traditions or appreciation for historical Islamic scholarship.
Qutb means 'pole' alone, while Qutbuddin specifically links this spiritual status to the Islamic faith, making it a complete religious identifier.
