"Moment of joy and pride... Saira ji sends me this: 'from Dilip saab to you with love from the hospital'," Amitabh wrote alongside the image.
The same image was shared by Dilip Kumar on the micro-blogging site on Monday.
Dilip Kumar was admitted to Lilavati hospital after he suffered high fever and vomiting.
