In Arabic, the name "Abd Allah" means "slave of Allah". One of his early titles, preceding his conversion to Islam, was "atiqe", "the saved one". Muhammad later reaffirmed this title when he said that Abu Bakr is the "atiqe" (the one saved from hell fire by God). He was called "Al-Siddiq" (the truthful) by Muhammad after he believed him in the event of Isra and Mi'raj when other people didn't, and Ali confirmed that title several times.
