In 1994, while serving as Assistant Professor at the Shari‘ah Academy of the International Islamic University, Islamabad, Dr. Amin conceived the idea of creating a private scholarly council of Islamic scholars from different schools of thought, aimed at developing consensus positions on socio-political issues and fostering inter-sectarian harmony. Inspired partly by the model of Imam Abū Ḥanīfah’s scholarly gatherings, he shared the idea with the late Dr. Mahmood Ahmad Ghazi (then Director General of the Shari‘ah Academy), who welcomed it. A few preliminary meetings were held in Islamabad, but circumstances required Dr. Amin to move to Lahore.

There, he took charge of the English and Arabic departments at Dār al-Islām, an institution run by his friend Abdul Malik Mujāhid of Riyadh, before later joining the Department of the Encyclopaedia of Islam at Punjab University as Senior Editor.

When the issue of interest (ribā) reached the Supreme Court’s Shariah Appellate Bench, presided over by Justice Khalil ur Rahman, the Court sought scholarly input. In response, Dr. Amin mobilized professors and researchers from Islamic Studies departments across the University to prepare collective submissions. These were formally presented to the Court through Majlis Fikr-o-Nazar.

Subsequently, Dr. Amin, under the same forum, engaged scholars from various schools of thought to review the madrasah curriculum, resulting in consensus-based recommendations and eventually a proposed new curriculum. These details are preserved in his book Hamārā Dīnī Niẓām-i-Ta‘līm (“Our Religious System of Education”).

In 2007, further efforts culminated in the establishment of the Millī Majlis Shari‘ī (“National Shari‘ah Council”), inaugurated at Jāmi‘ah Naeemiā, Lahore, with scholars from across the spectrum of religious schools. Its leadership over the years has included eminent figures such as the late Dr. Sarfaraz Naeemi, Mufti Muhammad Khan Qadri, and currently Mawlānā Zahid al-Rashīdī, with Dr. Amin serving as its Secretary-General.

Since its founding, the Majlis has issued hundreds of scholarly collective statements on diverse issues, promoted inter-sectarian harmony, and created a forum where scholars deliberate, pray, and share meals together. Although lacking funds, offices and staff, its intellectual impact is not very significant.
