لَا تُوجَدُ أَدِلَّةٌ كَثِيرَةٌ مِنَ الْقُرْآنِ الْكَرِيمِ وَالسُّنَّةِ النَّبَوِيَّةِ فَحَسْبُ، بَلْ إِنَّ مِنْهَا: قَالَ اللهُ تَعَالَى: {إِنَّ الَّذِينَ يَكْفُرُونَ بِاللهِ وَرُسُلِهِ وَيُرِيدُونَ أَنْ يُفَرِّقُوا بَيْنَ اللهِ وَرُسُلِهِ وَيَقُولُونَ نُؤْمِنُ بِبَعْضٍ وَنَكْفُرُ بِبَعْضٍ وَيُرِيدُونَ أَنْ يَتَّخِذُوا بَيْنَ ذَٰلِكَ سَبِيلًا}

A ---There are so many proofs from the Glorious Qur'an and the Prophetic Sunnah, some of which are: Allah the Almighty says: {Verily, those who disbelieve in Allah and His Messengers and wish to make distinction between Allah and His Messengers (by believing in Allah and disbelieving in His Messengers) saying, "We believe in some but reject others,” and wish to adopt a way in between.

أُولَٰئِكَ هُمُ الْكَافِرُونَ حَقًّا ۚ وَأَعْتَدْنَا لِلْكَافِرِينَ عَذَابًا مُّهِينًا ۝ وَالَّذِينَ آمَنُوا بِاللَّهِ وَرُسُلِهِ وَلَمْ يُفَرِّقُوا بَيْنَ أَحَدٍ مِّنْهُمْ أُولَٰئِكَ سَوْفَ يُؤْتِيهِمْ أُجُورَهُمْ ۚ وَكَانَ اللَّهُ غَفُورًا رَّحِيمًا} (النساء: 150-152)

They are in truth disbelievers. And We have prepared for the disbelievers a humiliating torment. And those who believe in Allah and His Messengers and make no distinction between any of them (Messengers), We shall give them their rewards; and Allah is Ever Oft-Forgiving, Most Merciful}. (An-Nisa', 150-152)

قال رسول الله ﷺ: «آمنتُ بالله ورسله». (رواه البخاري ومسلم)

Allah's Messenger (Peace be upon him) says: "I believed in Allah and His Messengers.” (Bukhari and Muslim)
