Hadith 47-12

حَدَّثَنا أَبي رَضِىَ اللهُ عَنْهُ قالَ: حَدَّثَنا سَعْدِ بْنِ عَبْدِ اللَّه عَنْ مُحَمَّدِ بْنِ عِيسَى بْنِ عُبِيْد عَنْ بشار قالَ: قالَ الرِّضا عَلَيْهِ السَّلامُ إِنَّ عَبْدَ اللَّهِ يَقْتُلُ مُحَمَّداً فَقُلْتُ لَهُ وَعَبْدُاللَّهِ بْنُ هَارُونَ يَقْتُلُ مُحَمَّدَ بْنَ هَارُونَ فَقَالَ لِي: نَعَمْ عَبْدُ اللَّهِ الَّذِي بِخُرَاسَانَ يَقْتُلُ مُحَمَّدَ بْنَ زُبَيْدَةَ الَّذِي هُوَ بِبَغْدَادَ فَقَتَلَه.

(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 Al-Husayn ibn Bashshar, “Ar-Ridha’ (a.s.) said, ‘Abdullah will kill Muhammad.’ I asked, ‘Will Abdullah ibn Harun kill Muhammad ibn Harun?’ Ar-Ridha’ (a.s.) said, ‘Yes. Now Abdullah who is in Khorasan will kill Muhammad ibn Zobayda who is in Baghdad.’ In fact, Al-Ma’mun killed Al-Amin. [8] ”
