9. Muḥammad ibn Ḥasan narrated to me from Muḥammad ibn Ḥasan Al-Saffār, from Aḥmad ibn Muḥammad ibn ‘Isā, from Aḥmad ibn Muḥammad ibn Abī Nasr Al-Bizanťi, who said: I read the following in the letter of Abil Ḥasan Al-Riďā : Tell my Shia that coming to my Ziyārah in the eyes of Allāh is equal to performing one thousand Hajj. So I asked Abā Ja’far (Imam Jawād ), “One thousand Hajj!?” Imam replied, “I swear to Allah, yes! And (the reward is) one million Hajj for those who go to his Ziyārah while knowing his rights.”
