Sunan Ibn Majah, Book 13, Hadith 20 (In-Book) ⓘ
It was narrated from Bara' bin 'Azib that the Messenger of Allah called one of the Jewish scholars and said: “ Swear by the One Who sent the Torah (Tawrah) down to Musa.”
حَدَّثَنَا عَلِيُّ بْنُ مُحَمَّدٍ، حَدَّثَنَا أَبُو مُعَاوِيَةَ، عَنِ الأَعْمَشِ، عَنْ عَبْدِ اللَّهِ بْنِ مُرَّةَ، عَنِ الْبَرَاءِ بْنِ عَازِبٍ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم دَعَا رَجُلاً مِنْ عُلَمَاءِ الْيَهُودِ فَقَالَ " أَنْشُدُكَ بِاللَّهِ الَّذِي أَنْزَلَ التَّوْرَاةَ عَلَى مُوسَى " .
