The Prophet’s practical implementation can show how an instruction of the Qur’an was carried out. A verse may state a command concisely while authenticated Sunnah explains its manner, extent, or practical form. This clarifies the relation between a concise statement and its authorized explanation.
Attribution to the Prophet requires reliable evidence. One then asks whether the action explains a binding requirement, illustrates a permissible form, or responds to a particular circumstance. A single event must not automatically be made obligatory for every setting.
Example: the practical details of acts of worship require study of authentic Prophetic teaching alongside the relevant Qur’anic commands.
