Al-Sayyid Mahmūd wrote Mafātih al-Sihha in which he gathered the medicine of the Prophet, may Allah bless him and his family, the medicine of the Imāms, and al-Risāla al-Dhahabiya along with little explanation in Persian, printed in al-Najaf al-Asraf in 379 A. H. Al-Sayyid Mirza Ali explained al-Risāla al-Dhahabiya in Persian. Al-Sayyid Husayn b. Nasr Allah al-Arūmi al-Mūsawi wrote Tarjamat al-Mūsawi fi al-Tibb al-Radawi .

Abū al-Qāsim Sahāb explained it in Persian and named the explanation as Bihdāsht Radawi , and it was printed at the end of volume one of his book Razandagani Hazrat Imām Ridā , peace be on him, pp. 301-350. Dr. al-Sayyid Sāhib Zayni explained al-Risālah (the dissertation) in the light of modern medicine, and the explanation was printed in the Multaqā al-Asrayn periodical series, in Baghdad. Abd al-Wāsi translated al-Risāla into Persian.

[1] As this dissertation is of great importance, it has been written in ancient calligraphy. An ancient copy, handwritten by Abd al-Rahmān b. Abd Allah al-Karkhi in 715 A. H., is available at the Imām al-Hakim Library, serial 237. [1] The translation in the script of the author is available at the Imām Amir al-Mu'minin Library, serial 237. 3.

Al-Mamūn praises the Golden Medical Dissertation Imām al-Ridā, peace be on him, sent his al-Risāla al-Dhahabiya (golden medical dissertation) to al-Mamūn, and he admired it and ordered it to be written in gold, to be copied many times, to be given to his sons, the members of his family, and the machinery of his government. He also ordered copies of it to be deposited at his depository of wisdom (Buyūt al-Hikma) .

Without doubt al-Risāla al-Dhahabiya was shown to the great physicians of his time, and they read it. Accordingly, al-Mamūn praised it through the following letter: In the Name of Allah, the Most Gracious, the Most Merciful. Praise belongs to Allah, Qualified for praise and its Guardian, the end and beginning of it belongs to him, the Possessor of blessings, favors, and kindness.

I praise Him for His uninterrupted blessings and favors, and I praise Him for His gifts and grants with a praise which gives rise to His increase and brings (me) near to Him. I bear witness that there is no god but Allah with the witness of one who is loyal to Him through belief, not of the one who denies His Lordship and Oneness; rather the witness which confirms His ascription to Himself; and that He is just as He, the Great and Almighty, says: Say: He, Allah, is One.
