In transmitting a Hadith, its wording is preserved together with the narrators through whom it was received. This sequence of narrators is the sanad (سند).
The narrator preserves the Hadith together with its sanad by:

• writing it down very carefully.
Such a narrator is called tāmm al-ḍabṭ (تام الضبط), fully precise in preservation. This includes careful written preservation, not memory alone.
