Allah is not mentioned in the Bible. He is a fictitious god. He is not alive. He is a figment of the imagination; A tool of Satan to damn people to hell. Read What the Bible says.
Deut 6:4 Hear, O Israel: The LORD our God is one LORD: Isa 45:21-22 Tell ye, and bring them near; yea, let them take counsel together: who hath declared this from ancient time? who hath told it from that time? have not I the LORD? and there is no God else beside me; a just God and a Saviour; there is none beside me. Look unto me, and be ye saved, all the ends of the earth: for I am God, and there is none else. Hos 13:4 Yet I am the LORD thy God from the land of Egypt, and thou shalt know no god but me: for there is no saviour beside me. Ps 83:18 That men may know that thou, whose name alone is JEHOVAH, art the most high over all the earth. Isa 44:6 Thus saith the LORD the King of Israel, and his redeemer the LORD of hosts; I am the first, and I am the last; and beside me there is no God. Deut 4:35 Unto thee it was shewed, that thou mightest know that the LORD he is God; there is none else beside him. Deut 4:39 Know therefore this day, and consider it in thine heart, that the LORD he is God in heaven above, and upon the earth beneath: there is none else. Deut 32:39a See now that I, even I, am he, and there is no god with me: Isa 43:10-11 Ye are my witnesses, saith the LORD, and my servant whom I have chosen: that ye may know and believe me, and understand that I am he: before me there was no God formed, neither shall there be after me. I, even I, am the LORD; and beside me there is no saviour. John 10:30 I and my Father are one. John 14:9 Jesus saith unto him, Have I been so long time with you, and yet hast thou not known me, Philip? he that hath seen me hath seen the Father; and how sayest thou then, Shew us the Father? 1 John 5:20 And we know that the Son of God is come, and hath given us an understanding, that we may know him that is true, and we are in him that is true, even in his Son Jesus Christ. This is the true God, and eternal life. John 8:58 Jesus said unto them, Verily,verily, I say unto you, Before Abraham was, I am.
If your god is one who accepts the existence of other gods, then your god is not the God of the Bible. The true God will not sacrifice truth for unity. Each person is free to make his choice. According to the Bible, any god other than the one presented in the Bible is a fictitious, false god.
