Allah is intended to be the same entity that jews and christians worship. The problem as always arises in whether you obey what he has directed you to do.
Deu 18:18 I will raise them up a Prophet from among their brethren, like unto thee, and will put my words in his mouth; and he shall speak unto them all that I shall command him.
Act 3:20-23 And he shall send Jesus Christ, which before was preached unto you: Whom the heaven must receive until the times of restitution of all things, which God hath spoken by the mouth of all his holy prophets since the world began. For Moses truly said unto the fathers, A prophet shall the Lord your God raise up unto you of your brethren, like unto me; him shall ye hear in all things whatsoever he shall say unto you. And it shall come to pass, that every soul, which will not hear that prophet, shall be destroyed from among the people.
Muslims aren't lying when they say Christ was a prophet... check out the references;
Mat 13:57 And they were offended in him. But Jesus said unto them, A prophet is not without honour, save in his own country, and in his own house.
Luk 13:33 Nevertheless I must walk to day, and to morrow, and the day following: for it cannot be that a prophet perish out of Jerusalem.
Joh 6:14 Then those men, when they had seen the miracle that Jesus did, said, This is of a truth that prophet that should come into the world.
Joh 7:16 Jesus answered them, and said, My doctrine is not mine, but his that sent me.
Joh 7:17 If any man will do his will, he shall know of the doctrine, whether it be of God, or whether I speak of myself.
Act 2:32 This Jesus hath God raised up, whereof we all are witnesses.
Act 2:33 Therefore being by the right hand of God exalted, and having received of the Father the promise of the Holy Ghost, he hath shed forth this, which ye now see and hear.
The prophet like Moses

The problem in this case is that they are not obeying God's instructions. There are many many more who do believe in Christ and yet still fail to obey God's commands. Catholocism has appointed a pope to speak with the authority of Christ. They have by law caused the sabbath day to become sunday and they have made it ok for people to worship Mary. No where in the bible have I ever read that God says its ok to do what you think is right as long as you believe in his Son. Christ did only that which his father commanded, we are expected be like Christ...
Luk 6:40 The disciple is not above his master: but every one that is perfect shall be as his master.
So even though the deity in this case is the same for many religions, the way you honor that deity counts. When one considers that belief is the only concern then obeying becomes a secondary thing with little power of effect. My mom spoke in the past about this very point when she said "The catholics raise hell all week, every week and then get forgiven on every sunday. I don't think this is right"
Well mom I have studied Gods word and I agree with you on this point. How you exist matters regardless of your beliefs.
Rom 2:13 (For not the hearers of the law are just before God, but the doers of the law shall be justified.
Rom 2:14 For when the Gentiles, which have not the law, do by nature the things contained in the law, these, having not the law, are a law unto themselves:
Rom 2:15 Which shew the work of the law written in their hearts, their conscience also bearing witness, and their thoughts the mean while accusing or else excusing one another;)
Rom 2:21 Thou therefore which teachest another, teachest thou not thyself? thou that preachest a man should not steal, dost thou steal?
Rom 2:22 Thou that sayest a man should not commit adultery, dost thou commit adultery? thou that abhorrest idols, dost thou commit sacrilege?
Rom 2:23 Thou that makest thy boast of the law, through breaking the law dishonourest thou God?
Rom 2:24 For the name of God is blasphemed among the Gentiles through you, as it is written.
Rom 2:25 For circumcision verily profiteth, if thou keep the law: but if thou be a breaker of the law, thy circumcision is made uncircumcision.
Rom 2:26 Therefore if the uncircumcision keep the righteousness of the law, shall not his uncircumcision be counted for circumcision?
Rom 2:27 And shall not uncircumcision which is by nature, if it fulfil the law, judge thee, who by the letter and circumcision dost transgress the law?
Rom 2:28 For he is not a Jew, which is one outwardly; neither is that circumcision, which is outward in the flesh:
Rom 2:29 But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.
If I believe in Christ and I am not a Jew is it ok to break Gods laws or disobey his commands? We cannot be saved by obeying the law as this is our duty to reflect the same "righteousness of the law" that Christ did. Christ made it clear that there is a spirit of the law when he was confronted about his disciples eating on the sabbath. Christ also made it clear that that the leaders had made the law a burden by not observing it in the spirit it was intended. At no time did he ever infer that Gods commands should not be obeyed.
He was always expanding the true understanding of the laws and commands to give us understanding of the nature of our heavenly Father.
