Chapter 10 | On The Reasons why Ali ibn Musa Ar-Ridha accepted the succession to the throne from Al-Ma’mun, what Went On, those who were displeased and those who were pleased
5 - حَدَّثَنا عَلِىِّ بْنِ عَبْدِ اللَّه الوَرَّاقُ رَضِىَ اللهُعَنْهُ قالَ: حَدَّثَنا عَلِىِّ بْنِ إِبراهِيمِ بْنِ هاشِم، عَن أَبيهِ، عَن عَبْد السَّلامُ بْنِ صالِح الهَرَوِيِّ قالَ وَاللَّهِ مَا دَخَلَ الرِّضَا a.sُ فِي هَذَا الأَمْرِ طَائِعاً وَقَدْ حُمِلَ إِلَى الْكُوفَةِ مُكْرَهاً ثُمَّ أُشْخِصَ مِنْهَا عَلَى طَرِيقِ الْبَصْرَةِ وَفَارِسَ إِلَى مَرْوَ.
40-5 Ali ibn Abdullah al-Var’raq - may God be pleased with him - narrated that Ali ibn Ibrahim ibn Hashem quoted on the authority of his father, on the authority of Abdil Salam ibn Salih al-Harawi, “By God! Ar-Ridha’ did not accept this affair willingly. He was unwillingly taken to Kufa, then he was taken to Marv by way of Basra and Fars.”
