Hadith (plural: Ahadith): literally means a saying or a statement. It refers to statements (or narrations) that are attributed to Prophet Muhammad (ﷺ/peace be upon him). These include:
what the Prophet ﷺ said (his statements)
What he ﷺ did (his actions), and
what was done by others (around him) andhe accepted that action.
The ahadith have been narrated by the Prophet's ﷺ companions, and have reached us through individual, reliable narrator(s) in every generation. The authenticity of a hadith is derived from the narrators (whether they were trustworthy, honest, had good memory etc). Sahih in Arabic is a term used to describe authenticity.
Sunnah (plural: sunanah):literally means a path, method or way. The sunnah contains the religious practices that are established by the Prophet ﷺ. The (authentic) ahadith helps to establish and provide evidence for the sunnah.
The established and authentic sunnah are as reliable as the Qur’an. Therefore, the Qur’an and the Sunnah remain our two primary sources of understanding Islam.
