The Source of Traditions on Imam al-Riḍā (Vol 1) · Hadith 33 (#Ḥadīth #24)

24 - نَصُّ آخَرُ: حَدَّثَنا أَبي رَضِىَ اللهُ عَنْهُ قالَ: حَدَّثَنا سَعْدُ بْنِ عَبْدِ اللَّهِ، عَنْ مُحَمَّدِ بْنِ عِيسَى بْنِ عُبِيْدٍ، عَنْ يُونُس بْنِ عَبْدُ الرَّحْمنِ، عَنِ الحُسَيْنِ بْنِ الُمخْتارِ قالَ: لَمّا مَرَّ بِنا أَبُوالحَسَن a.sُ بِالْبَصْرَةِ خَرَجَت إِلَيْنا مِنْهُ أَلْواحٌ مَكْتُوب فِيها بِالعَرْضِ عَهْدِي إِلىأَكْبَرِ وُلْدِي».

4-24 In another tradition we read that (The author of the book narrated) my father - may God be pleased with him - narrated that Sa’d ibn Abdillah, on the authority of Muhammad ibn Isa bin Obayd, on the authority of Yunus ibn Abdurrahman, on the authority of Al-Hussein ibn al-Mokhtar, “When Abul Hassan (Imam Al-Kadhim) (s) passed by Basra, we received letters from him (s) in which it was written, ‘My successoris my oldest son (Ali ibn Musa Al-Ridha (s)).’”
