Hausa language
Kala Kato is a Quranist movement whose adherents reside mostly in northern Nigeria, with some adherents residing in Niger. Kala Kato means a "man says" in the Hausa language, in reference to the sayings, or hadiths, posthumously attributed to the Islamic prophet Muhammad. Kala Kato accepts only the Quran as authoritative and believe that anything that is not Kala Allah, which means what "God says" in the Hausa language, is Kala Kato.
