The "Piku" star said he had a word with the 93-year-old actor's wife Saira Banu about his health.
"Saira ji informs me that he (Dilip Kumar) is doing fine, by the grace of the Almighty... Prayers for a speedy recovery...," he posted on Twitter.
Kumar was admitted to the hospital yesterday morning after he complained of respiratory problems.
Banu had said they had to take him to the hospital as he was suffering from high fever and chest infection since April 15 night.
He was last seen in the film "Qila" in 1998.
Kumar was awarded the Dadasaheb Phalke award in 1994 and the Padma Vibhushan in 2015.
