Sayyid Kamāl al-Ḥaydarῑ was born in the holy city of Karbalā’ in the year 1956. He was raised in an educational environment, and completed his elementary, middle and high school education in Karbalā’ while simultaneously attending lessons on Tajwῑd and studies of the Holy Qur’an under MullaJāsem al-Ḥumayrῑ. He was a distinct student and preferred over his peers by his teacher. As a result, he would substitute for his teacher at the time of his absence. His interest in Ḥawza studies began in Karbalā’ wherein he completed the introductory levels (muqaddimāt) under Shaykh Ḥusayn ’al-‘uthyān and Shaykh ‘Ali al-‘uthyān. He then moved to the holy city of Najaf to pursue his academic and religious studies. He completed his academic studies in the Faculty of Jurisprudence earning a Bachelor of Islamic Studies in the year 1987.
Along with his academic studies, his love and passion for Hawza studies drove him to complete the level ofṣuṭuḥ al-‘āliyah under the following teachers:
1) The martyr Ayatullah ‘abdel Ṣaḥeb al-Ḥakῑm.
2) Ayatullah Shaykh Bashῑr al-Najafῑ.
As for his teachers under whom he studied Baḥth al-Khārej, they are the following:
1) Grand Ayatullah Sayyid Muḥammad Bāqir al-Ṣadr.
2) Grand Ayatullah Sayyid Abul-Qāsim al-Mousawῑ al-Khu’ῑ.
3) His Eminence Sayyid Muḥammad Taqῑ al-Ḥakῑm.
4) His Eminence Ayatullah Shaykh Mῑrza ‘Alῑ al-Gharawῑ.
5) His Eminence Ayatullah Sayyid Nasrullah al-Mustanbt.
This is in regards to his study of jurisprudence (al-fiqh) and the principle of jurisprudence (usul ʾal-fiqh.) As for his philosophical and theological interests, he attempted to nourish them by attending the lessons of Sayyid Muslim al-Ḥellī and Shaykh ʿAbbas al-Qochānī.
When the situation in Najaf worsened and the grip on the scholars intensified, Sayyid Kamāl departed from Najaf and went to Kuwait. After a short while, he finally settled in the holy city of Qum which is considered to be the center of the Ḥawza’s in Iran and the center of jurisprudence, knowledge and gnosis.
From the beginning of the year 1983, Sayyid Kamāl pursued his Ḥawza studies on all levels. He attended Ayatullah al-ʿUthma Shaykh Waḥīd al-Khorāsānī’s lectures from the beginning of the subject of qatʿ and until the end of the course on Usul (principles of Islamic jurisprudence). He also attended the entire study of the subject of “ṣalāt” in the jurisprudential field under Ayatullah al-ʿUthma Shaykh Waḥīd al-Khorāsānī’s for six years. He also attended the lessons of Ayaotllah ʾal-ʿUthma Shaykh Mīrzā Jawād Tabrīzī for two years.
In addition to studying under these two scholars, he also attended Baḥth Khārij in the book of al-makāsib under Shaykh Mourtadha al-Ḥāʾerī, the son of Shaykh ʿAbdulKarīm al-Hāʾerī (the founder of the Islamic Seminary in the holy city of Qum).
As for the philosophical and gnosis (‘irfan) arena, he pursued his educational journey by attending the lessons of a group of the most profound and prominent scholars such as his eminence Ayatullah Shaykh Jawādi Amolī and his eminence Ayatullah Shaykh Ḥassan Zāda Amolī. He also benefited from attending the lessons and lectures of Ayatullah Mesbāḥ Yazdī.
