وَعَنْ جَابِرٌ عَنِ النَّبِيِّ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ حِينَ أَتَاهُ عُمَرُ فَقَالَ إِنَّا نَسْمَعُ أَحَادِيثَ مِنْ يَهُودَ تُعْجِبُنَا أَفْتَرَى أَنْ نَكْتُبَ بَعْضَهَا؟ فَقَالَ: «أَمُتَهَوِّكُونَ أَنْتُمْ كَمَا تَهَوَّكَتِ الْيَهُودُ وَالنَّصَارَى؟ لَقَدْ جِئْتُكُمْ بِهَا بَيْضَاءَ نَقِيَّةً وَلَوْ كَانَ مُوسَى حَيًّا مَا وَسِعَهُ إِلَّا اتِّبَاعِي» . رَوَاهُ أَحْمد وَالْبَيْهَقِيّ فِي كتاب شعب الايمان

Jabir told that when ‘Umar came to the Prophet saying, “We hear from Jews traditions which charm us, so do you think we should write down some of them ?” he replied, “Are you in a state of confusion as the Jews and the Christians were? I have brought them to you white and pure, and if Moses were alive he would feel it absolutely necessary to follow me.” Ahmad transmitted it, and also Baihaqi in Shu’ab al-iman.
