Living Sunnah and controlled writing
- The Companions directly heard, observed and practised the Prophet’s ﷺ teachings.
- Hadith was preserved mainly through memorisation, repetition, teaching and practice.
- Some Companions also wrote personal notes, but the Qur’an remained the central written revelation.
- The Prophet ﷺ was alive to correct misunderstandings, so the Sunnah was learnt in context.
