Sarkar was born in 1894, to a Bengali Muslim family in Sadullapur, Gaibandha, which was then part of the Rangpur District of the Bengal Presidency. He was involved in the Swadeshi movement, which disrupted his education and led to his arrest in 1911. He was later released and passed his matriculation in 1915. He then studied further, gaining a Bachelor of Law degree.^[2]
