Once again people referred to Al-Sayyid Hasan al-Sadr and repeated their requests, he published his manual of practical laws titled as Ru'us al-masa'il al-muhimma and undertook this responsibility at the age of sixty six [11].

Scientific Works and Cultural Activities

The book Ta'sis al-Shi'a li-'ulum al-Islam

Al-Sayyid Hasan al-Sadr wrote eighty two volumes of books, the most famous one of which is Ta'sis al-Shi'a. In this book, he tried to explain how Shi'a has been pioneer in different Islamic sciences comparing to other Islamic sects based on documents.

In Tarikh adab al-lughat al-'Arabiyya published in four volumes, Jurji Zaydan, the famous historiographer (d. 1914) wrote, "Shi'a was a small sect who had no significant works and now there is no Shi'a in the world".

When al-Sayyid Hasan al-Sadr heard about this, promised to work together with Shaykh Aqa Buzurg Tihrani and Ayatollah Muhammad Husayn Kashif al-Ghita' to introduce Shi'a. Al-Sayyid Hasan al-Sadr researched about Shi'a scientific activities and their roles in foundation and perfection of Islamic sciences and compiled his famous work titled Ta'sis al-Shi'a li-'ulum al-Islam which was published in 1370/1950-1 in 445 pages.

By writing al-Dhari'a ila tasanif al-Shi'a in twenty nine volumes, Shaykh Aqa Buzurg Tihrani introduced Shi'a writings and works in different sciences[12]

Wahhabi cultural activities were increasing everyday. To remove this trouble, al-Sayyid Hasan al-Sadr wrote a book titled as Risalat al-sharifa fi radd 'ala fatawa al-Wahhabiyyin.

He loved to buy and collect books so much. His love for that was so much he put aside some necessary expenses in his life in order to be able to buy even one book. He collected old books and manuscripts and if the author of a book was unknown, he searched so much to find its author. His library now holds more than thousand volumes of precious books.

'Allama Sharaf al-Din says, "I heard from al-Sayyid Hasan al-Sadr that he was (usually) awake to study all nights in his youth; and during the day, he did not take a nap before or after noon. I also witnessed that when he was old, he was busy in his library researching and writing, holding a pen in his right hand and a paper in his left hand. I even dare to say his honorable slept [only] one fourth of his life and was awake the rest of his life, contrary to ordinary people who are awake one fourth of their lives"[13].


Al-Sayyid Hasan al-Sadr passed away on Thursday, Rabi' I 11, 1354/June 13, 1935 and was buried in one of the rooms of the courtyard of Kadhimiyya shrine beside his father's grave[14]. Following his demise, Sayyid Abu al-Hasan Isfahani announced public mourning for three days[15].
