“I am English by education, Muslim by culture and Hindu merely by accident.”
While this is often attributed to Nehru, it was actually something said by the Hindu Mahasabha leader, N. B. Khare.
Khare states, "Nehru’s is a very complex personality. As he himself has explained in his Autobiography, he is English by education, Muslim by culture and Hindu by an accident of birth."
"The Angry Aristocrat", N. B. Khare in A Study of Nehru, Rafiq Zakaria (ed.), 1960.
No such passage exists in Nehru's autobiography. https://www.altnews.in/did-jawaharlal-nehru-ever-say-i-am-english-by-education-muslim-by-culture-and-hindu-by-accident/
