*Some people have the impression that Nazrul named his last two sons "Kazi Shabyashachi" and "Kazi Anirudhdha" without Islam at the end. For them the following information might be helpful.
"After the death of his infant son, Bulbul, neither of the two other sons of Nazrul, Sunny and Nini (Kazi Shabyashachi ISLAM and Kazi Anirudhdha ISLAM) are alive any longer." [Dr. Sushilkumar Gupta, Nazrul-Choritmanosh: Calcutta, De's Publishing, 1988, p. 106]
