Hazrat Moulana Abul Hasan ‘Ali Nadwi (rahmatullahi alaih) writes:
In my knowledge, the person to liven and revive the method of our pious predecessors in this era was Moulana Husain Ahmad Madani (rahmatullahi alaih). Upon the request of his close associates and students he made it a standard habit of spending the entire month of Ramadhaan in one place where many people from surrounding and far-off areas of the country would gather. For many years Hazrat would spend the entire month of Ramadhaan in Silhat. Thereafter, Hazrat spent Ramadhaan for several years in Baaskandi (Bengal). For a few years he spent the month of Ramadhaan in his hometown, Ilaah-daad Poorah. At all these venues, his mureeds and associates would gather in large numbers and they would all be treated as his guests. Hazrat himself would lead the taraaweeh salaah. Those present would engage in zikr, tilaawat, etc. with extreme enthusiasm and vigour. His associates would experience great spiritual conditions and realise immense progress. For long periods thereafter they would remember and discuss the eventful moments that they had experienced. If Allah Ta‘ala had willed and granted Moulana a longer life, this system would have continued in Ilaah-daad Poorah for many years later and Allah Ta‘ala alone knows how many servants would have reached their goal (of proximity to Allah Ta‘ala). However, this system discontinued with the demise of Hazrat Moulana in 1377 A.H. – 1957 leaving many in utter grief and distress.
