Al‑Kashi reports fifty books by al-Hasan alone and al‑Najashi mentions thirty books between the two, saying: “The sons of Sa'id compiled excellent and useful books, and they are thirty in number.” Al-Husayn joined hands with his brother al-Hasan in writing the thirty books but Al-Husayn is more renowned for them than his brother; and these books are: Kitab al-Wuďu' (The Book of Ablutions) Kitab al-Salat (The Book of Prayers) Kitab al-Zakat (The Book of Alms) Kitab al-Sawm (The Book of Fasting) Kitab al-Hajj (The Book of Pilgrimage) Kitab al-Nikah (The Book of Marriage) Kitab al-Talaq (The Book of Divorce) Kitab al-`Itq wa'l-Tadbir wa'l-Mukatabah (The Book of Manumission of Slaves, Management and Correspondence) Kitab al-Ayman wa'l-Nudhur (The Book of Oaths and Vows) Kitab al-Tijarat wa'l-Ijarat (The Book of Trade and Leasing) Kitab al-Khums (The Book of Islamic Tax) Kitab al-Shahadat (The Book of Testimonies) Kitab al-Sayd wa'l-Dhaba`ih (The Book of Game and Slaughtered Animals) Kitab al-Makasib (The Book of Earnings) Kitab al-Ashribah (The Book of Drinks) Kitab al-Ziyarat (The Book of Pilgrimages) Kitab al-Taqiyah (The Book of Dissimulation) Kitab al-Radd `Ala'l-Ghulah (The Book of Refuting the Extremists) Kitab al-Manaqib (The Book of Virtues) Kitab al-Mathalib (The Book on Slandering) Kitab al-Zuhd (The Book of Asceticism) Kitab al-Muru'ah (The Book of Chivalry) Kitab Huquq al-Mu'minin wa-Fadhlihim (The Book concerning the Rights and Excellencies of Believers) Kitab Tafsir al-Qur'an (The Book of the Exegesis of the Qur'an) Kitab al-Wasaya (The Book of Bequests) Kitab al-Fara'idh (The Book of Obligations) Kitab al-Hudud (The Book of Legal Punishments) Kitab al-Diyat (The Book of Blood Money) Kitab al-Malahim (The Book of Battles) Kitab al-Du'a` (The Book of Supplications) Al-Husayn ibn Yazid al‑Surani used to say: “al-Hasan is a partner to his brother Al-Husayn in all of the latter's chain of narrators except concerning Zur'ah ibn Muhammad al‑Haďrami and Faďalah ibn Ayyub, where Al-Husayn used to narrate through his brother from these two.”[^7] Their maternal uncle, Ja'far ibn Yahya ibn Sa'd al‑Ahwal, was amongst the companions of Abu Ja'far al‑Thani (Imam al‑Jawad [a.s]).

Thus, the members of this household were known for their profound faith in Allah, the Most High, and their sincerity towards Him; and also their true love for the Messenger of Allah and his pure progeny [a.s].
