[3] As desired by the then NUCLEUS (Shadhin Bangla Biplobi Parishad) by a match stick and yellow-coloured paint, he marked the map of Bangladesh over the red circle of the proposed flag in the room numbered 108 of the then Iqbal Hall of Dhaka University (DU) from midnight of 6 June until dawn of 7 June 1970.

A. S. M. Abdur Rab, Shajahan Siraj, Kazi Aref Ahmed, Manirul Islam, Swapan Kumar Choudhury, Quamrul Alam Khan (Khasru), Hasanul Haq Inu, Yousuf Salahuddin Ahmed and some others were also involved in it and present at that time.

On behalf of the NUCLEUS, the same flag was unfurled by Abdur Rab along with AFM Mahbubul Haq, Das and other student league leaders from the roof top of the western porch of the Arts Faculty of DU, on 2 March 1971, shortly before the outbreak of the Bangladesh Liberation War.

Artist Quamrul Hassan was asked to report on the design, colour, shape and explanation.

On 17 January 1972, the new design was made the official national flag of Bangladesh.
