Apne Nainon Ko Samjhade - Jeetendra & Mumtaz - Maa Aur Mamta(1970)

http://en.wikipedia.org/wiki/Maa_Aur_Mamta
Father Henry (Rehman) entrusts a newly-born infant in the care of an unwed Maya (Nutan), leaving her to explain the presence of the child. She is literally thrown out of the village and runs away to Bombay. There she is taken care of by a kind-hearted Muslim taxi-driver (Jayant). Years later, the child grows up to be called Ram (Jeetendra), but the question haunting everyone's mind is who is Ram's biological father?
