Allah says, the People of the Book know what you brought them, O Muhammad , as they know their own children. This is because they received good news from the previous Messengers and Prophets about the coming of Muhammad , his attributes, homeland, his migration, and the description of his Ummah. Allah said next,

﴿الَّذِينَ خَسِرُواْ أَنفُسَهُم﴾

(Those who have lost (destroyed) themselves) and thus incurred the ultimate loss,

﴿فَهُمْ لاَ يُؤْمِنُونَ﴾

(will not believe.) in this clear matter. A matter about which the previous Prophets gave good news, and a matter extolled about in ancient and modern times. Allah said next,

﴿وَمَنْ أَظْلَمُ مِمَّنِ افْتَرَى عَلَى اللَّهِ كَذِباً أَوْ كَذَّبَ بِـَايَـتِهِ﴾

(And who does more wrong than he who invents a lie against Allah or rejects His Ayat) meaning, there is no person more unjust than he who lies about Allah and claims that Allah has sent him, while Allah did not send him. There is no person more unjust than he who denies Allah's proofs, signs and evidences,

﴿إِنَّهُ لاَ يُفْلِحُ الظَّـلِمُونَ﴾

(Verily, the wrongdoers shall never be successful.) Surely, both of these people will never acquire success, whoever falsely ﴿claims that Allah sent him﴾ and whoever refuses ﴿Allah's Ayat﴾.

﴿وَيَوْمَ نَحْشُرُهُمْ جَمِيعاً ثُمَّ نَقُولُ لِلَّذِينَ أَشْرَكُواْ أَيْنَ شُرَكَآؤُكُمُ الَّذِينَ كُنتُمْ تَزْعُمُونَ - ثُمَّ لَمْ تَكُنْ فِتْنَتُهُمْ إِلاَّ أَن قَالُواْ وَاللَّهِ رَبِّنَا مَا كُنَّا مُشْرِكِينَ - انظُرْ كَيْفَ كَذَبُواْ عَلَى أَنفُسِهِمْ وَضَلَّ عَنْهُمْ مَّا كَانُواْ يَفْتَرُونَ - وَمِنْهُمْ مَّن يَسْتَمِعُ إِلَيْكَ وَجَعَلْنَا عَلَى قُلُوبِهِمْ أَكِنَّةً أَن يَفْقَهُوهُ وَفِى ءَاذَانِهِمْ وَقْراً وَإِن يَرَوْاْ كُلَّ ءَايَةٍ لاَّ يُؤْمِنُواْ بِهَا حَتَّى إِذَا جَآءُوكَ يُجَـدِلُونَكَ يَقُولُ الَّذِينَ كَفَرُواْ إِنْ هَـذَآ إِلاَّ أَسَـطِيرُ الاٌّوَّلِينَ - وَهُمْ يَنْهَوْنَ عَنْهُ وَيَنْأَوْنَ عَنْهُ وَإِن يُهْلِكُونَ إِلاَّ أَنفُسَهُمْ وَمَا يَشْعُرُونَ ﴾

(22. And on the Day when We shall gather them all together, We shall say to those who joined partners in worship (with Us): "Where are your partners (false deities) whom you used to assert (as partners in worship with Allah)'') (23. There will then be (left) no Fitnah for them but to say: "By Allah, our Lord, we were not those who joined others (in worship with Allah).'') (24. Look! How they lie against themselves! But the (lie) which they invented will disappear from them.) (25. And of them there are some who listen to you; but We have set veils on their hearts, so they understand it not, and deafness in their ears; if they see every one of the Ayat they will not believe therein; to the point that when they come to you to argue with you, those who disbelieve say: "These are nothing but tales of the men of old.'') (26. And they prevent others from him and they themselves keep away from him, and (by doing so) they destroy none but themselves, yet they perceive (it) not.)
