What is your advice to the Christians, in order to know the truth and believe in the prophethood of Muhammad pbuhap through the Gospel?
Answer: My advice to every free Christian to know the truth is to make the words of Jesus pbuh his standard:
[14 Now he was casting out a demon that was mute . When the demon had gone out, the mute man spoke, and the people marveled. 15 But some of them said, “He casts out demons by Beelzebul, the prince of demons,” 16 while others, to test him, kept seeking from him a sign from heaven . 17 But he, knowing their thoughts, said to them, “Every kingdom divided against itself is laid waste, and a divided household falls. 18 And if Satan also is divided against himself, how will his kingdom stand?”] Luke Chapter Eleven.
So those who believe in the Gospel, let them read some passages of the Quran and contemplate them justly. Then, in the light of the previous Gospel text, can you consider these passages to be satanic the way those who have no concern except insulting Muhammad pbuhap?
And these are examples from the Quranic passages:
﴾Invite to the way of your Lord with wisdom and good instruction, and argue with them in a way that is best . Indeed, your Lord is most knowing of who has strayed from His way, and He is most knowing of . . who is guided ﴿Surat an-Nahl (The Bee) 16:125
﴾Worship Allah and associate nothing with Him, and to parents do good, and to relatives, orphans, the needy, the near neighbor, the neighbor farther away, the companion at your side, the traveler, and those whom your right hands possess.Indeed, Allah does not like those . .who are self-deluding and boastful ﴿ Surat an-Nisa (The Women) 4:36
﴾And do not turn your cheek toward people and do not walk through the earth exultantly.Indeed, Allah does not like everyone self-deluded and boastful ﴿ Surat Luqman (Luqman) 31:18
﴾In order that you not despair over what has eluded you and not exult over what He has given you. And Allah does not like everyone self-deluded and boastful.﴿Surat al-Hadid (The Iron) 57:23.
Let them read these verses from Surat al-Isra (The Night Journey) and ask themselves:
Does Satan call for the worship of Allah alone? Does Satan call for good manners and kindness to parents and to the poor and spending money and helping those in need of help; and does he forbid murder and adultery and violating the money of the orphan; and does he command fulfilment of the promise and full measure?
And if Satan commands these kind ethics, then what does Allah swt command from their point of view?
Are these not the commandments of all the prophets and the wisdom which they brought from Allah:
﴾Do not make with Allah another deity and become censured and forsaken. And your Lord has decreed that you do not worship except Him, and to treat the parents well. Whether one or both of them reach old age [while] with you, do not say to them so much as “uff” and do not repel them but speak to them a noble word. And lower to them the wing of humility out of mercy and say, “My Lord, have mercy upon them as they brought me up when I was small.” Your Lord is most knowing of what is within yourselves. If you should be righteous — then indeed He is Forgiving toward those who return to Him. And give the relative his right, and [also] the poor and the traveler, and do not spend wastefully. Indeed, the wasteful are brothers of the satans, and ever has Satan been to his Lord ungrateful. 28And if you turn away from the needy in anticipation of your Lord’s mercy, then say to them a kind word. And do not make your hand as chained to your neck or extend it completely and thereby become blamed and insolvent. Indeed, your Lord extends provision for whom He wills and restricts it. Indeed He is ever Knowing and Seeing concerning His servants. And do not kill your children for fear of poverty. We provide for them and for you. Indeed, their killing is great sin. And do not approach adultery. Indeed, it is ever an immorality and is evil as a way. And do not kill the soul which Allah has forbidden, except by right. And whoever is killed unjustly — We have given his guardian authority, but let him not exceed limits in taking life. Indeed, he has been supported. And do not approach the money of an orphan, except in the way that is best, until he reaches maturity. And fulfill the covenant. Indeed, the covenant is ever questioned. And give full measure when you measure, and weigh with an even balance.That is the best and best in result. And do not pursue that of which you have no knowledge. Indeed, the hearing, the sight and the heart — about all those one will be questioned. And do not walk upon the earth exultantly .Indeed, you will never tear the earth, and you will never reach the mountains in height. The evil of all that is dested in the sight of your Lord. That is from what your Lord has revealed to you of wisdom. And do not make with Allah another deity, lest you be thrown into Hell, blamed . .and banished ﴿ Surat al-Isra (The Night Journey) 17:22-39
Shame on the Christians and what a shame and a disgrace to neglect the words of Jesus: [“Every kingdom divided against itself is laid waste, and a divided household falls. And if Satan also is divided against himself, how will his kingdom stand?”], and not make them a standard by which they measure what came in the Quran so that they would know that it is from Allah.
Is this not the standard of Jesus pbuh, so why turn away from it?! Do you believe in parts of your book and disbelieve in others?
Look at the Quran and contemplate the wisdom it contains, the calling to good and to the possession of kind and honored ethics, so how can it be from the foolish Satan who calls to evil and to the dispraised ethics; is Satan divided against himself? Is the kingdom of Satan divided against itself?
Is this not how Jesus pbuh taught you to distinguish truth from falsehood? Are you incapable of distinguishing between wisdom and foolishness, between good and evil, between kind ethics and dispraised ethics?
And do you believe that Satan and his kingdom is divided against itself, so at one time it calls for good and at another time for evil? At one time for honored ethics and at other times for dispraised ethics?
[“Every kingdom divided against itself is laid waste, and a divided household falls . And if Satan also is divided against himself, how will his kingdom stand?” ].
So I advise every Christian who fears the evil consequence to pay attention to the fact that what their Churches are presenting today, which is that Jesus is an absolute deity, was previously denied by many of the Christians including Arius, and they are among the major Christian clerics. There were and still are many Christians such as Jehovah’s witnesses who do not believe in this false and foolish ideology which is rejected by the Gospel and reasoning. And I have clarified its falsehood in The Book of Monotheism using a Gospel passage that does not allow for interpretation and confusion, and with the clear evident intellectual proof.
 Refer to Appendices 1 and 2. As for the passage, in The Book of Monotheism he pbuh said, “The clear statement from the Gospel, 'Jesus pbuh does not know the Hour': Jesus says about himself that he does not know the Hour in which the Minor Resurrection occurs: [32 “But concerning that day or that hour, no one knows, not even the angels in heaven, nor the Son, but only the Father.” ] Mark Chapter 13. And ignorance is an imperfection while the absolute deity is perfect and absolute and He is not defected by imperfection or ignorance, because He is light within which there is no darkness, as ignorance defects the creation due to the existence of darkness in the page of his existence; therefore, Jesus pbuh is light and darkness and this proves the point that Jesus is not an absolute deity; but, rather a worshipper created from darkness and light, and he is not light within which there is no darkness, Allah is far above that. And in this there is the clear statement and a clarification and a preaching to those of reasoning.”
