[3] Naser had a prosperous clearing and forwarding agency in the erstwhile East Pakistan.

His business was destroyed by the Pakistan Army, rendering him penniless, and Naser fled to neighboring India with nothing but the clothes on his back.

The former communications minister and Muslim League leader Abdus Sabur Khan reportedly attempted to bribe Naser to convince his brother Mujib to accept the 4-point program of General Yahya Khan.

Naser refused to accept the bribe and exclaimed that Mujib would rather die than sacrifice his principles.

Naser was said to have closely resembled his older brother Sheikh Mujibur Rahman.

[17][18] Naser was accused of being a ringleader of syndicates smuggling jute to India during the presidency of Mujib.
