Comrade Tarin was born in 1901 to a rural family of the Tarin/Tareen tribe settled in Rehana village, Haripur District, Hazara, NWFP. His father was Abdul Jabbar Khan, a village Lambardar and government revenue collector and he tried to give Tarin as good an education as he could afford. On finishing his college studies, Tarin was not interested like most young men of the time in either seeking a government job or enrolling in the British Indian Army. Instead, he was inspired by the Khilafat Movement and sought to go to Kabul, Afghanistan, and try from there to reach Turkey, and strive in the cause of the Islamic Ottoman Caliphate.
In 1920, Tarin and some of his young companions managed to make it to Kabul and there, they found that the Khilafat Movement was quite moribund and that most so-called 'Muhajireen' (immigrants from India, in the cause of Islamic Jihad) were merely languishing in the Afghan capital.
At this time, Tarin met and was considerably impressed by some young Hindus from India, who were planning to go to join MN Roy in Moscow, USSR and he was converted to the dynamic Communist perspectives for change in the British Indian colony. He also joined these young men and went with them and eventually ended up joining MN Roy and his senior associates in Tashkent in the then Soviet Turkestan and was present at the founding of the Communist Party of India there, in October 1920.
Tarin and some 12 or 13 other young men were indoctrinated and trained in Communist sabotage techniques and sent back to India, in early 1922, and crossed into the NWFP via the Pamirs. On reaching Peshawar, however, they were soon betrayed and arrested as the Punjab CID had received advance notice of their arrival and alerted the local police.
Tarin and most of his companions were tried and sentenced to hard labour under the article 121-A of the Indian Penal Code, for trying to 'instigate' sedition and revolt against the King-Emperor's rule in India. However, they were mostly released after two years, in 1924, and Tarin returned home to his native village at this time although surveillance on him continued until 1925.
