"Didn't get to see HNY but saw the smiling faces of all who saw it. I pray to Allah that it delivers happiness to the viewers," Shah Rukh tweeted.
The movie was screened in Mumbai Sunday.
Directed by Farah Khan, the movie also features Deepika Padukone, Abhishek Bachchan, Boman Irani, Jackie Shroff, Vivaan Shah and Sonu Sood.
The film is produced by Shah Rukh's Red Chillies Entertainments Pvt. Ltd.
SRK says the idea is to produce films "which are difficult to produce".
"'Paheli' was offbeat, 'Asoka' and 'Ra.One' were difficult to produce. I had a visual effects company, so I could make them. I have to make films that are commercially viable," he said.
