About Muhammad Zakariyya Kandhalvi:
Mu?ammad Zakar?y? ibn Mu?ammad Ya?yá ?idd?q? K?ndhlaw? Sah?ranp?r? Muh?jir Madan? was a Sunni Hanafi Islamic scholar of the Deobandi school of Islamic thought in India, particularly known as a scholar of hadith and an influential ideologue of Tablighi Jamaat, the missionary and reform movement founded by his uncle, Maulana Muhammad Ilyas. The writings of Zakariya constitute much of the group's basic reading material in the form of Faza'il-i A`mal. Originally composed in Urdu but translated into several languages, Faza'il-i A`mal contains several of his treatises on the virtues of different subjects, including Faza'il-i Qur'an (Virtues of the Qur'an), Faza'il-i Ramazan (Virtues of Ramadan), and Faza'il-i Namaz (Virtues of Salah). Also notable among his works, which number over one hundred, are Awjaz al-Masalik, an Arabic commentary in six volumes on Imam Malik's Muwatta, and Khasa'il-i Nabawi, an Urdu translation and commentary on Imam at-Tirmidhi's Shama'il.
