Who is Allah ?
Allah is the proper name, which applies to the true God Who exists necessarily by Himself, Who is named with all the excellent Divine names and qualified by all attributes of perfection. Allah is One and Unique. He has neither a wife, nor a son nor a partner, nor an equal. He is the sole creator and the Rubb of the universe
Some prefer th translate the Arabic term, ' Rubb' into 'Lord'. Beside the fact that the latter is a Biblical term referring to the alleged lordship of the slave of Allah, Prophet Eesa (Jesus) may Allah exalt his mention, the word 'lord' which is limited to 'master, 'chief', 'proprietor', or 'ruler', can never convey the conclusive signification of the term 'Rubb' means, the One Who gives life and causes death, the Creator, the Fashioner, the Provider, the One upon Whom all creatures depend for their means of subsistence.
