Muhammad ibn Ismail as-San’ani (1099 AH – 1182 AH / 1687 – 1768 CE) was a historian, poet, and author from Sana’a. He was one of the later imams of Yemen, considered among the few independent mujtahids (qualified jurists) who adhered to the evidence from the Quran and Sunnah, alongside Salih al-Muqbali, al-Hasan al-Jalal, and as-Shawkani. He was born in the city of Kahlan, near Sana’a. He then moved to Sana’a at the age of eleven and grew up there. He authored many works, amounting to about one hundred. Among them are: Subul al-Salam, a commentary on Bulugh al-Maram min Adillat al-Ahkam by Ibn Hajar al-Asqalani; Tawdih al-Afkar, a commentary on Tanqih al-Anzar; al-Yawaqit fi al-Mawaqit, a commentary on al-Jami’ al-Saghir by al-Suyuti; Irshad al-Nuqqad ila Taysir al-Ijtihad; and al-Rawd al-Nadhir. He died in Sana’a.
