Hausa language
Kala Kato is a Quranist movement whose adherents reside mostly 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 Muhammad. Kala Kato accept 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.
