17 - حَدَّثَنا أَبُو عَلِي الحُسَيْنِ بْنِ أحْمَد الْبِيْهَقِيُّالْحاكِم قالَ حَدَّثَني مُحَمَّدِ بْنِ يَحْيَى الصُّوليُّ قالَ: حَدَّثَنا الحَسَن بْنِ الجَهْمِ قالَ حَدَّثَني أَبي قالَ صعد الْمَأمُون المِنْبَر لَمّا بايِع عَلاىِّ بْنِِلرِّضا a.sُ فَقالَ: أَيُّهَا النَّاسِ جاءَتكم بيعة عَلِىِّ بْنِ مُوسَى بْنِ جَعْفَرِ بْنِ عَلِىِّ بْنِ الحُسَيْن بْنِ عَلِىِّ بْنِ أَبي طالِب a.sُ وَاللَّه لَوْ قُرأَت هذِهِ الأسماء عَلَى الصُّم البُكم لبرءوا بإذن اللَّه عَزَّ وَجَلَّ.
40-17 Abu Ali Al-Husayn ibn Ahmad al-Bayhaqi narrated that Muhammad ibn Yahya al-Sowli quoted on the authority of Al-Hassan ibn Al-Jahm, on the authority of his father, “When Al-Ma’mun pledged allegiance to Ali ibn Musa Ar-Ridha’ , he climbed up the pulpit and said, ‘O people! You were informed of the news of the pledge of allegiance to Ali ibn Musa ibn Ja’far ibn Muhammad ibn Ali ibn Al-Husayn ibn Ali ibn Abi Talib. By God, if they read these names to the deaf and dumb, they will be healed by the permission of God the Honorable the Exalted.’”
