Tacit and Explicit Testimony as proof of abu al-Hassan al-Rida’s عليه السلام Divine Authority over the people after abu al-Hassan Musa عليه السلام

9. A number of our people has narrated from Ahmad ibn Muhammad from Ali ibn al-Hakam from ‘Abdallah ibn al-Mughirah from al-Husayn ibn al-Mukhtar who has said the following. “In Basra (wherein the Imam عليه السلام was imprisoned) certain tablets came out to us from abu al-Hassan عليه السلام on which, it was written horizontally, ‘My instructions and directives to the my eldest son (Ali ibn Musa al-Rida عليه السلام who should give such and such to so and so. As far so and so is concerned do not give him anything until I will come or Allah, the Most Holy, the Most High, will decree that I must die, Allah certainly does what He wills.”
