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.

The punishment of the grave was heard and made manifest onto others. (See Hayat al-Sahabah 3/777,841). In the same manner, the washing off of sins in wudu is something we believe in because of the hadith of the Messenger of Allah (may Allah bless him and give him peace), although it is also part of the unseen. The ahadith mentioned in the book Fazail Aamaal written by Hazrat Shaikhul Hadith Maulana Zakariay (Rahimahullah) are neither mauzoo (fake) nor lies. All the ahadith mentioned therein are credible in Fazail chapter as per the rule of muhadditheen (scholars of Hadith). Therefore, those who blame it they are wrong and tell lie. For further clarity, let it be understood that the task of authenticating Ahaadith of Rasulullah (Sallallaahu Alayhi Wasallam) is dependent on the individual theological conclusions of the Masters of Hadith. That is why the possibility of differences of opinions always exists. Hence, it is possible that this particular Hadith was acceptable to Shaykhul Hadith Moulana Muhammad Zakariyyah Kandhlawi (RA), who was also a great authority in the field of Hadith.

Sa’d ibn Abi al-Waqqas (may Allah be pleased with him) said regarding the verse: “ who delay their sal ā h from their stated fixed times” they are those who delay their sal āh from their fixed times. The hadīth was graded sound [sah ī h] yet stopped [mawquf] meaning a tradition that stops at a Companion by al-H ākim and al-Bayhaqi (may Allah have mercy on them).
