Chander, who is also a flautist, on Tuesday tweeted: "Md. Rafi was one of the greatest singers of India and needs no certificate from anyone. If you are a Rafi fan, boycott this movie."
Rafi's son Shahid, has already criticised the film's director Karan for including a dialogue in the film that he found insulting to his star father.
In the movie, actress Anushka Sharma says: "Mohammed Rafi gaate nahi, rote the (Mohammed Rafi used to cry, not sing).
“This is so insulting. I am ashamed of Karan Johar..” -Mohd Rafi’s son Shahid on ADHM dialogue!
Chander also posted: "I am musically connected to Rafi Saheb and play his songs on flute. Any utterance against a great singer hurts his millions of fans like me."
Mohammed Rafi, who has delivered innumerable hit songs like "Kya hua tera wada", "Baharon phool barsao", "Likhe jo khat tujhe" and "Chura liya hai tumne jo dil ko", died in 1980.
The late singer had worked with producer Yash Johar -- Karan Johar's father -- in the 1980 film "Dostana" for which he sang "Mere dost qissa yeh kya ho gaya" and "Salamat rahe dostana".
