The Prophet ﷺ said: “The most beloved of your names to Allah are ʿAbd Allah and ʿAbd al-Rahman” (Muslim 2132), and scholars add to them all names formed on a name of Allah. The name al-Jabbar occurs 1 times in the Quran; its page in the 99 Names section gives its meaning and verses. Egypt’s Dar al-Iftaʾ lists “al-Jabbar” alone among the names proper to Allah that are not given to a man (fatwa 13118).
ʿAbd al-Jabbar joins ʿabd with al-Jabbar, from the root j-b-r, which expresses both a force that prevails and the act of mending what is broken (jabara, “to set a bone”): the One whose will is done and who consoles broken hearts. Applied to a man, jabbar means a tyrant: that is why the name is always ʿAbd al-Jabbar, never “Jabbar” alone.
He is Allāh, other than whom there is no deity, the Sovereign, the Pure, the Perfection, the Grantor of Security, the Overseer, the Exalted in Might, the Compeller, the Superior. Exalted is Allāh above whatever they associate with Him.
