Mumbai: On Father's Day on Sunday, actor Irrfan Khan took his son Ayaan to Sabarmati Ashram in Ahmedabad to pay an ode to Father of the Nation Mahatma Gandhi. Irrfan, awaiting release of "Madaari", also narrated to his son the motivational story of Gandhi's principles and how he played a prominent role in the fight for freedom. The father-son duo even tried their hands at the charkha, a spinning wheel, at the Sabarmati Ashram. The authorities even handed over a rule book of the ashram to Ayaan, which has in it the teachings of Mahatma Gandhi. Joyous with his father's idea of taking him to the ashram, Ayaan said: "I want to know more about Gandhiji. It feels great that I have come here with my father, at the place of 'Father of the Nation' on Father's Day." Irrfan, who is married to screen writer Sutapa Sikdar, has two sons -- Ayaan and Babil. The "Maqbool" star, who gained global recognition with performances in films like "Slumdog Millionaire", "Life of Pi" and "Jurassic World", will also soon be seen in the film "Inferno" alongside Hollywood star Tom Hanks.
