The correct definition,is the first which is clarified in the Book of Allah (may He be Praised) many times. For instance, Allah (may He be Praised) states, You (Alone) we worship, and You (Alone) we ask for help (for each and everything). and, And your Lord has decreed that you worship none but Him. He (may He be Praised) also states, And I (Allâh) created not the jinn and mankind except that they should worship Me (Alone). and, That is because Allâh — He is the Truth (the only True God of all that exists, Who has no partners or rivals with Him), and what they (the polytheists) invoke besides Him, it is Bâtil (falsehood).
There are many Ayahs (Qur’anic verses) to this effect. Moreover, this is the meaning that the polytheists understood from ‘La ilaha illa Allah’, when the Prophet (peace be upon him) called them to it, saying: O my people, say ‘La ilaha illa Allah’, to succeed.
