Sahih Muslim 2380 b
Sa, id b. jubair reported that it was said to Ibn 'Abbas that Nauf al-Bikali was of the opinion that Moses who went in search of knowledge was not the Moses of Bani Isra'il. He said:
Sa'id, did you hear it from him? I said: Yes. Thereupon he said that Nauf had not stated the fact.
حَدَّثَنِي مُحَمَّدُ بْنُ عَبْدِ الأَعْلَى الْقَيْسِيُّ، حَدَّثَنَا الْمُعْتَمِرُ بْنُ سُلَيْمَانَ التَّيْمِيُّ، عَنْ أَبِيهِ،
 عَنْ رَقَبَةَ، عَنْ أَبِي إِسْحَاقَ، عَنْ سَعِيدِ بْنِ جُبَيْرٍ، قَالَ قِيلَ لاِبْنِ عَبَّاسٍ إِنَّ نَوْفًا يَزْعُمُ أَنَّ
 مُوسَى الَّذِي ذَهَبَ يَلْتَمِسُ الْعِلْمَ لَيْسَ بِمُوسَى بَنِي إِسْرَائِيلَ ‏.‏ قَالَ أَسَمِعْتَهُ يَا سَعِيدُ قُلْتُ
 نَعَمْ ‏.‏ قَالَ كَذَبَ نَوْفٌ ‏.‏
