The call of the Qur’an and previous books is one

All-Ankabūt (The Spider)

وَلَا تُجَادِلُوا أَهْلَ الْكِتَابِ إِلَّا بِالَّتِي هِيَ أَحْسَنُ إِلَّا الَّذِينَ ظَلَمُوا مِنْهُمْ وَقُولُوا آَمَنَّا بِالَّذِي أُنْزِلَ إِلَيْنَا وَأُنْزِلَ إِلَيْكُمْ وَإِلَهُنَا وَإِلَهُكُمْ وَاحِدٌ وَنَحْنُ لَهُ مُسْلِمُونَ {٤٦}

Do not argue with the People of the Book except in the best manner, unless with those of them who transgress [against you]. And say, “We believe in what is sent down to us and what was sent down to you, and our God and your God is One, and to Him we submit.”

وَكَذَلِكَ أَنْزَلْنَا إِلَيْكَ الْكِتَابَ فَالَّذِينَ آَتَيْنَاهُمُ الْكِتَابَ يُؤْمِنُونَ بِهِ وَمِنْ هَؤُلَاءِ مَنْ يُؤْمِنُ بِهِ وَمَا يَجْحَدُ بِآَيَاتِنَا إِلَّا الْكَافِرُونَ {٤٧}

Thus We have sent down to you the Book. Those to whom We gave the Scripture believe in it, and from these [pagans] there are some who believe in it, and none rejects Our verses except the disbelievers.

وَمَا كُنْتَ تَتْلُو مِنْ قَبْلِهِ مِنْ كِتَابٍ وَلَا تَخُطُّهُ بِيَمِينِكَ إِذًا لَارْتَابَ الْمُبْطِلُونَ {٤٨}

You [O Prophet] never recited any book before this, nor did you write with your hand. Otherwise, the people of falsehood would have raised suspicions.

بَلْ هُوَ آَيَاتٌ بَيِّنَاتٌ فِي صُدُورِ الَّذِينَ أُوتُوا الْعِلْمَ وَمَا يَجْحَدُ بِآَيَاتِنَا إِلَّا الظَّالِمُونَ {٤٩}

Rather, this [Qur’an] is clear verses [preserved] in the hearts of those who have been given knowledge. And none rejects Our verses except the wrongdoers.

وَقَالُوا لَوْلَا أُنْزِلَ عَلَيْهِ آَيَاتٌ مِنْ رَبِّهِ قُلْ إِنَّمَا الْآَيَاتُ عِنْدَ اللَّهِ وَإِنَّمَا أَنَا نَذِيرٌ مُبِينٌ {٥٠}

They say, “Why is it that no signs have been sent down to him from his Lord?” Say, “The signs are only with Allah, and I am only a clear warner.”

أَوَلَمْ يَكْفِهِمْ أَنَّا أَنْزَلْنَا عَلَيْكَ الْكِتَابَ يُتْلَى عَلَيْهِمْ إِنَّ فِي ذَلِكَ لَرَحْمَةً وَذِكْرَى لِقَوْمٍ يُؤْمِنُونَ {٥١}

Is it not enough for them that We have sent down to you the Book which is being recited to them? Indeed, there is a mercy and reminder in it for people who believe.

قُلْ كَفَى بِاللَّهِ بَيْنِي وَبَيْنَكُمْ شَهِيدًا يَعْلَمُ مَا فِي السَّمَاوَاتِ وَالْأَرْضِ وَالَّذِينَ آَمَنُوا بِالْبَاطِلِ وَكَفَرُوا بِاللَّهِ أُولَئِكَ هُمُ الْخَاسِرُونَ {٥٢}

Say, “Allah is Sufficient as a Witness between me and you. He knows all that is in the heavens and earth. Those who believe in falsehood and disbelieve in Allah, it is they who are the losers.”
