[1][2] He was a founding member of Jamia Millia Islamia, New Delhi, and was on its foundation committee, which was headed by Mahmud Hasan Deobandi.

Then, Dehlawi was sent with a letter of recommendation from his teacher, 'Ubaidul Haq, to the administrator of the Madrasa 'Arabiya at Shahi Masjid in Muradabad.

Because of his memory and intelligence, he did not exert as much effort but quickly overtook his classmates and earned the highest marks on his examinations.

While at Madrasa 'Ainul 'Ilm, Dehlawi also started a monthly periodical, Al Burhan, in response to the Qadianis.

Besides teaching hadith and answering fatwas, Dehlawi managed the organizational affairs of the madrasa.

After fifty years, Dehlawi had answered hundreds of thousands of fataawa and his rulings are a treasure to fiqh.

It was for this reason that he was renowned among common folk as well as the officials of the courts of law, who would prefer his rulings in religious cases.

The eloquence and grandeur of the poem were such that Dehlawi was requested to produce an Urdu translation with footnotes, providing more details than and explaining difficult words from the original.

Dehlawi’s most renowned publication is Ta'limul Islam, four volumes of questions and answers for children as well as adults in simple language.

[1] During his final years, due to what he saw as the deterioration of morality in society, clashes between Hindus and Muslims, and other reasons, Dehlawi withdrew from politics and became reclusive, not even giving public comment.

[citation needed] In his final months, he suffered severe liver illness, despite medical treatment.

[4] Dehlawi‘s students include Muhammad Taqi Amini, Izaz Ali Amrohi.
