To know the meaning of God is obvious its essential for those who wish to tell others about Islam. But sadly many can’t answer when asked what is the meaning of God for Muslims
The Meaning of ‘God’, and Spiritual Realization
In the Name of Allah, Most Merciful and Compassionate
God: the one in no need of anyone else, whom all else are in absolute need of. [Bajuri, Hashiyat al-Sanusiyya]
This definition of ‘god’ is a formal definition of the scholars of the science of `aqida, chosen by authorities like Imam Sanusi and most of the later Ash`ari scholars after him.
As for the linguistic basis, this was discussed by Imam Raghib al-Isfahani in his authoritative explanation of the vocabulary of the Qur’an, Mufradat Alfadh al-Qur’an. He explained that the root verb alaha refers to worship. Thus, ilah (‘god’) refers to ‘the one worshipped.’ [Isfahani, Mufradat, 82]
