Mu?ammad Zakariya ibn Mu?ammad Ya?yá ?iddiqi Kandhlawi Saharanpuri Muhajir Madani (Mu?ammad Zakariya ibn Mu?ammad Ya?yá a?-?iddiqi al-Kandahlawi as-Saharanfuri al-Madani; 2 February 1898 – 24 May 1982) was a Sunni Hanafi Hadith scholar of the Deobandi school of Islamic thought in India, popularly known as a "Hazrat Shaykh al-Hadith" and an influential ideologue of Tablighi Jamaat, the missionary and reform movement founded by his uncle Maulana Muhammad Ilyas.
His notable works 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.
Shaykh Zakariya was born at Kandhla in 1898, to Maulana Muhammad Yahya.
He spent ten years in Gangoh, where he attended his father's madrasah.
In 1910, he moved to Saharanpur to study at Mazahir Uloom Saharanpur, a madrasah closely affiliated with Darul Uloom Deoband.
He learned hadith from his father and from Khalil Ahmad Saharanpuri.
After graduating in 1915, he secured a position as a teacher at the school.
Shaykh Zakariya was also a prominent Sufi Shaykh of the Sabiri-Imdadi branch of the Chishti order.
He was a khalifah (spiritual successor) of Maulana Saharanpuri, who initiated him in the Sufi path in 1915 and gave him permission to initiate others in the four major tariqas (Chishtiyah, Naqshbandiyah, Suhrawardiyah, and Qadiriyah) in 1925.
He taught at Mazahir Uloom Saharanpur from 1916 to 1969, becoming well known by the title "Shaykh al-Hadith", a title given to him by his shaykh, Maulana Saharanpuri, for his extensive knowledge in the field of hadith.
After he stopped teaching due to developing cataracts, he focused on the spiritual training of his numerous disciples.
In 1973, he permanently migrated to Medina, Saudi Arabia, where he died in 1982.
His thousands of international students and disciples include his beloved student and disciple and khalifah (spiritual successor), Shaykh al-Hadith Maulana Yusuf Motala, who is a teacher of Hadith to many Ulama and a spiritual guide to thousands worldwide.
