Allah is an Arabic word and the meaning of this is “The One God”. Muslims believe in one God and conclude that everything is created by one supreme power. In Islam, Allah word is related to this supreme power. The Khuda is the same thing but is a Persian word and also used for god in the Urdu language . Both words Allah and Khuda have the same meanings but have different origins. People use the “ Khuda ” word in different languages and many South Asian Muslims use this word. As this word is originated in Pre-Islamic so most of the people use only the “Allah” word for God in Islam.
