وَعَنْهُ أَيْضًا أَنَّ عُمَرَ بْنَ الْخَطَّابِ رَضِيَ اللَّهُ عَنْهُ أَتَى النَّبِيَّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ بِكِتَابٍ أَصَابَهُ مِنْ بَعْضِ أَهْلِ الْكِتَابِ فَقَرَأَهُ عَلَى النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَآلِهِ وَسَلَّمَ فَغَضِبَ فَقَالَ: ((أَتَمَهَوَّكُونَ فِيهَا يَا عُمَرَ بْنَ الْخَطَّابِ؟ وَالَّذِي نَفْسِي بِيَدِهِ! لَقَدْ جِئْتُكُمْ بِهَا بَيْضَاءَ نَقِيَّةً، لَا تَسْأَلُوهُمْ عَنْ شَيْءٍ فَيُخْبِرُوكُمْ بِحَقٍّ فَتُكَذِّبُوا بِهِ أَوْ بِبَاطِلٍ فَتُصَدِّقُوا بِهِ، وَالَّذِي نَفْسِي بِيَدِهِ! لَوْ أَنَّ مُوسَى حَيًّا مَا وَسِعَهُ إِلَّا أَنْ يَتَّبِعَنِي))
Sayyiduna Jabir bin Abdullah (may Allah be pleased with them both) narrates that Sayyiduna Umar bin Khattab (may Allah be pleased with him) came to the Noble Prophet (peace and blessings be upon him) with a book which he had obtained from some people of the Book, and he began to read it to him. The Prophet (peace and blessings be upon him) became angry and said: “O Umar bin Khattab! Have you fallen into doubt regarding your religion? By Him in Whose Hand is my soul! I have brought to you a Shari’ah that is clear, pure (and free from doubt and suspicion). Do not ask anything from the people of the Book, otherwise it may happen that they tell you something true and you deny it, or they tell you something false and you affirm it. By Him in Whose Hand is my soul! If Musa (peace be upon him) were alive, even he would have no choice but to follow me.”
