The Arabic word ibadah (عبادة) or ibada (usually translated "worship") means service or servitude. It is connected with related words such as "Ubudiyyah" ("slavery") and has connotations of obedience, submission and humility. The word linguistically means "obedience with submission". In terms of Islam, ibadah is the obedience, submission and devotion to Allah along with the ultimate love for Allah. Muslims believe that ibadah is the reason for the existence of all humanity.
