Allah is a Common Noun.Allah is Not Proper Noun. So Allah is not the name of God. The other name of God is Almighty. Say 'Allahu' instead of Allah. Here Al means 'The', Lah means 'No', Hu means 'But'. So here Hu is Allah's Attribute. Hu is perfect Attribute of Allah free from all Associations. Now I am saying this Allah's attribute 'Hu'. Whether my understanding is correct?.
In Arabic 'Hu' means He; The None (but) He - is the absolute meaning of Al-la-hu.
