Hadith 4-24

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 عَلَيْهِ السَّلامُ بِالْبَصْرَةِ خَرَجَت إِلَيْنا مِنْهُ أَلْواحٌ مَكْتُوب فِيها بِالعَرْضِ عَهْدِي إِلى أَكْبَرِ وُلْدِي».

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-Husayn ibn al-Mokhtar, “When Abul Hassan (Imam Al-Kazim) (a.s.) passed by Basra, we received letters from him (a.s.) in which it was written, ‘My successor is my oldest son (Ali ibn Musa Al-Ridha’ (a.s.)).’”
