Syed Muhammad Ishaq

Ishaq was a supporter of Bangladeshi independence. During the Bangladesh Liberation War of 1971, Mohammad Abdul Jalil (commander of Sector 9), Captain Abdul Latif and other Barisali freedom fighters would seek advice and duas from Muhammad Ishaq in Charmonai. His institution, Jamia Rashidia Ahsanabad, became a base for Bengali freedom fighters where they would stay and return from battles. The institution provided two large rooms for the freedom fighters to use and accommodated for them. For the entirety of the nine-month war, several government officials based in Barisal would shelter themselves with their families at the Charmonai Madrasa.

After returning to Bengal, Ishaq dedicated his life to teaching the Islamic sciences. In 1932, he founded the Charmonai Ahsanabad Rashidia Madrasa and Lillah Boarding (Orphanage) from his own home. It was named after his uncle Syed Ahsan and the Deobandi jurist Rashid Ahmad Gangohi respectively. He independently taught the Dars-i Nizami syllabus, before retiring in 1947. After 1947, through the efforts of Muhammad Esmatullah and his son-in-law Delwar Husain, the institution became an alia madrasa. Among his students were Syed Fazlul Karim, Muhammad Abul Bashar of Shahtali and Azharul Islam Siddiqi of Manikganj.

Syed Muhammad Ishaq (Bengali: সৈয়দ মুহম্মদ এছহাক; 1915–1977) was a Bangladeshi Islamic scholar, author, mufassir, debator and educationist. He was a disciple of Muhammad Ibrahim of Ujani. Ishaq was the inaugural Pir Saheb of Charmonai (Bengali: পীর সাহেব চরমোনাই), having founded the Charmonai Darbar Sharif and Jamia Rashidia Ahsanabad in 1924, one of the largest Islamic institutions in South Bengal. He was succeeded by his son, Syed Fazlul Karim, and became posthumously known by his followers as Dada Huzur.

Ishaq was born in 1915 to a Bengali Muslim family of Syeds in the village of Pashurikathi in Char Monai, located to the east of the Kirtankhola river in Backergunge District, Bengal Province. His father, Syed Amjad Ali, traced his lineage to Ali, the fourth Caliph of Islam. His great great grandfather, Syed Ali Akbar, migrated from Baghdad to Bengal, settling in the village of Pashurikathi in Barisal. Akbar's younger brother, Syed Ali Asghar, founded the Syed family of Laktia, located west of the Kirtankhola.
