Rangina Rasul or Rangeela Rasool (Urdu: رنگیلا رسول, Devanagari: रंगीला रसूल, english: Colourful Prophet) is a book published anonymously in Urdu in 1924. The book was considered highly controversial due to its satire of the marital life of the Islamic prophet Muhammad. Its publication led to reforms in India's penal code that made blasphemy illegal and may have contributed to promote the partition of India.
