He made the call while addressing a meeting at the Ministry of Foreign Affairs marking the birthday of Bangamata Sheikh Fazilatunnesa Mujib and son of Bangabandhu Sheikh Kamal.
A documentary based on Bangamata and Sheikh Kamal was screened at the meeting.
Foreign Minister Momen said the courage, firm stance and inspiration of Bangamata helped Bangabandhu achieve many things easily.
"We all know the activities of Bangamata nicely depicted in the Unfinished Memoirs of Bangabandhu," he said.
He said Sheikh Kamal, a very humble person and a gentleman, played a significant role for his country in his only 26 years life.
Dr Momen urged all to read books on Bangabandhu to know about him deeply.
Speaking as special guest, State Minister for Foreign Affairs M Shahriar Alam said Bangamata was the nucleus of Bangabandhu family.
The way Bangamata built up the family is something to be followed by at home and abroad as a shining example, he said.
Shahriar said the way Bangamata became a worthy associate of Bangabandhu was something which was impossible without any God-gifted special power.
He said the memory of Bangabandhu had been removed from various places including from national archives, BTV and Ress Information Department.
After the discussion, a doa was offered seeking salvation of departed souls of all martyrs including Bangabandhu Sheikh Mujibur Rahman, Bangamata Sheikh Fazilatunnesa Mujib and Sheikh Kamal.
Former ambassador Shahed Reza spoke as key discussant at the meeting attended by senior officials including Foreign Secretary Masud Bin Momen.
