14 - حَدَّثَنا أَبي قالَ: حَدَّثَنا سَعْدِ بْنِ عَبْدِ اللَّه عَنْمُحَمَّدِ بْنِ عِيسَى بْنِ عُبِيْد عَنْ مُحَمَّدِ بْنِ أَبي يعقوب عَنْ مُوسَى بْنِ هارُون قالَ رَأَيْتُ الرِّضَا a.sُ وَقَدْ نَظَرَ إِلَى هَرْثَمَةَ بِالْمَدِينَةِ فَقَالَ كَأَنِّي بِهِ وَقَدْ حُمِلَ إِلَى هَارُونَ فَضُرِبَتْ عُنُقُهُ فَكَانَ كَمَا قَالَ.

47-14 (The author of the book narrated) my father - may God be pleased with him - narrated that Sa’d ibn Abdullah quoted on the authority of Muhammad ibn Isa ibn Obayd, on the authority of Muhammad ibn Abi Yaqoob, on the authority of Musa ibn Harun, “I saw that Ar-Ridha’ looked at Harthamat ibn A’ayan and said, ‘It is as if I see that he is taken to Marv and is beheaded.’ That’s exactly what happened.”
