It has been said that when Ayatollah Sayyed Kamāl al-Ḥaydarῑ attended the Baḥth ‘al-Khārej lessons of Ayatollah Sayyed Muḥammad Bāqir ‘al-Ṣadr, he – S. Kamāl – was not wearing a turban and it was then when Sayyed ‘al-Ṣadr requested from him to wear the turban so that his attendance becomes formal.
This is in regards to his study of jurisprudence (ʾal-fiqh) and the principle of jurisprudence (ʾusul ʾal-fiqh.) As for his philosophical and theological interests, he attempted to nourish them by attending the lessons of Sayyed Muslim ʾal-Ḥellī and Sheikh ʿAbbas ʾal-Qochānī.
