Abd Allah (Arabic: عبد الله, romanized: ʻAbd Allāh), also spelled Abdullah, Abdhullah, Abdellah, Abdollah, Abdallah, Abdulla, Abdalla and many others, is an Arabic theophoric name meaning servant of God or "God's follower".
It is built from the Arabic words ʻabd (عبد) and Allāh (الله).
The variants Abdollah and Abdullah represent the elision of this "a" following the "u" of the Classical Arabic nominative case (pronounced [o] in Persian).
Humility before God is an essential value of Islam, hence Abdullah is a common name among Muslims.
Abdullah ibn Saba was a Yemenite Jew during the spread of Islam.
