The Holy Quran, Chapter Al-i'Imran - آل عمران

أَفَغَيْرَ دِينِ اللّهِ يَبْغُونَ وَلَهُ أَسْلَمَ مَن فِي السَّمَاوَاتِ وَالأَرْضِ طَوْعاً وَكَرْهاً وَإِلَيْهِ يُرْجَعُونَ

Seek they other than the religion of Allah, when unto Him submitteth whosoever is in the heavens and the earth, willingly, or unwillingly, and unto Him they will be returned.

وَإِذْ أَخَذَ اللّهُ مِيثَاقَ النَّبِيِّيْنَ لَمَا آتَيْتُكُم مِّن كِتَابٍ وَحِكْمَةٍ ثُمَّ جَاءكُمْ رَسُولٌ مُّصَدِّقٌ لِّمَا مَعَكُمْ لَتُؤْمِنُنَّ بِهِ وَلَتَنصُرُنَّهُ قَالَ أَأَقْرَرْتُمْ وَأَخَذْتُمْ عَلَى ذَلِكُمْ إِصْرِي قَالُواْ أَقْرَرْنَا قَالَ فَاشْهَدُواْ وَأَنَاْ مَعَكُم مِّنَ الشَّاهِدِينَ

When Allah made (His) covenant with the Prophets, (He said): Behold that which I have given you of the Scripture and knowledge. And afterward there will come unto you a messenger, confirming that which ye possess. Ye shall believe in him and ye shah help him. He said: Do ye agree, and will ye take up My burden (which I lay upon you) in this (matter)? They answered: We agree. He said: Then bear ye witness. I will be a witness with you.

مَا كَانَ لِبَشَرٍ أَن يُؤْتِيَهُ اللّهُ الْكِتَابَ وَالْحُكْمَ وَالنُّبُوَّةَ ثُمَّ يَقُولَ لِلنَّاسِ كُونُواْ عِبَاداً لِّي مِن دُونِ اللّهِ وَلَـكِن كُونُواْ رَبَّانِيِّينَ بِمَا كُنتُمْ تُعَلِّمُونَ الْكِتَابَ وَبِمَا كُنتُمْ تَدْرُسُونَ

It is not (possible) for any human being unto whom Allah had given the Scripture and wisdom and the Prophethood that he should afterwards have said unto mankind: Be slaves of me instead of Allah; but (what he said was): Be ye faithful servants of the Lord by virtue of your constant teaching of the Scripture and of your constant study thereof.

إِنَّ الَّذِينَ يَشْتَرُونَ بِعَهْدِ اللّهِ وَأَيْمَانِهِمْ ثَمَناً قَلِيلاً أُوْلَـئِكَ لاَ خَلاَقَ لَهُمْ فِي الآخِرَةِ وَلاَ يُكَلِّمُهُمُ اللّهُ وَلاَ يَنظُرُ إِلَيْهِمْ يَوْمَ الْقِيَامَةِ وَلاَ يُزَكِّيهِمْ وَلَهُمْ عَذَابٌ أَلِيمٌ

Lo! those who purchase a small gain at the cost of Allah's covenant and their oaths, they have no portion in the Hereafter. Allah will neither speak to them nor look upon them on the Day of Resurrection, nor will He make them grow. Theirs will be a painful doom.

وَمِنْ أَهْلِ الْكِتَابِ مَنْ إِن تَأْمَنْهُ بِقِنطَارٍ يُؤَدِّهِ إِلَيْكَ وَمِنْهُم مَّنْ إِن تَأْمَنْهُ بِدِينَارٍ لاَّ يُؤَدِّهِ إِلَيْكَ إِلاَّ مَا دُمْتَ عَلَيْهِ قَآئِماً ذَلِكَ بِأَنَّهُمْ قَالُواْ لَيْسَ عَلَيْنَا فِي الأُمِّيِّينَ سَبِيلٌ وَيَقُولُونَ عَلَى اللّهِ الْكَذِبَ وَهُمْ يَعْلَمُونَ

Among the People of the Scripture there is he who, if thou trust him with a weight of treasure, will return it to thee. And among them there is he who, if thou trust him with a piece of gold, will not return it to thee unless thou keep standing over him. That is because they say: We have no duty to the Gentiles. They speak a lie concerning Allah knowingly.

وَلاَ تُؤْمِنُواْ إِلاَّ لِمَن تَبِعَ دِينَكُمْ قُلْ إِنَّ الْهُدَى هُدَى اللّهِ أَن يُؤْتَى أَحَدٌ مِّثْلَ مَا أُوتِيتُمْ أَوْ يُحَآجُّوكُمْ عِندَ رَبِّكُمْ قُلْ إِنَّ الْفَضْلَ بِيَدِ اللّهِ يُؤْتِيهِ مَن يَشَاءُ وَاللّهُ وَاسِعٌ عَلِيمٌ

And believe not save in one who followeth your religion. Say (O Muhammad): Lo! the guidance is Allah's guidance. that any one is given the like of that which was given unto you or that they may argue with you in the presence of their Lord. Say (O Muhammad): Lo! the bounty is in Allah's hand. He bestoweth it on whom He will. Allah is All Embracing, All Knowing.

يَا أَهْلَ الْكِتَابِ لِمَ تَلْبِسُونَ الْحَقَّ بِالْبَاطِلِ وَتَكْتُمُونَ الْحَقَّ وَأَنتُمْ تَعْلَمُونَ

O People of the Scripture! Why confound ye truth with falsehood and knowingly conceal the troth?
