Latest review from Aftab Mirza
Also known as Markaz Ahle Hadees, Byculla.
This Masjid is 170 years old and its Imām was the great Scholar, al-`Allāmah as-Shaykh Muhammad Dāwūd Rāz رحمة الله عليه (d.1981), who himself was the Khalifah of Shaykh al-lslām Thanã' Allāh Amritsarī رحمه الله (d.1367 AH).
This is the very same Masjid, which King Sa`ud رحمه الله (d.1388 AH) visited in the year 1955, and lead the Ahl al-Hadīth in Salāh.
-- Shaykh Zulfiqâr Ibrahîm Memon حفظه الله
PS: As of what is apparent, this is the Masjid referred by the Shaykh.
والله أعلم بالصواب.
