22. Abu Sa’id Muhammad ibn al-Fadl ibn Muhammad ibn Ishaq al-Mudhakkar al-Naysaburi said in Naysabur, that Abu `Ali al-Hasan ibn `Ali al-Khazraji al-Ansari al-Sa`di related to me that `Abd al-Salam ibn Salih Abu al-Salt al-Hirawi said: I was with `Ali ibn Musa al-Rida when he was setting off for his journey from Naysabur and was riding a grey coloured mule, while Muhammad ibn Rafi, Ahmad ibn Harb, Yahya ibn Yahya, Ishaq ibn Rahawayh, and a number of other scholars were holding on to the bridle of his mule in Marba’ah. Thus, they all requested: “With respect to your pure forefathers, relate to us a tradition that you have heard from your father.” He leaned his head out of the camel-borne sedan, and he was wearing a woven fabric gown with two designs. He said: My father, the Pious Servant (of Allah) [al-`Abd al-Saleh], Musa ibn Ja’far, related to me that; My father, Ja’far ibn Muhammad related to me that: My father, Abu Ja’far Muhammad ibn `Ali al-Baqir (Opener of the Knowledge of the Prophets) related to me that: My father, `Ali ibn al-Husayn the Master of Servants of Allah related to me that: My father, the Master of the youth of Heaven al-Husayn related that: The Prophet said: Allah, Glorified be He, said: “Verily, I am Allah, and there is no god but Me; therefore, serve Me. Whoever bears true witness that `There is no god but Allah’ shall enter my Fortress, and whoever enters My Fortress is safe from My Chastisement.”
