بعد ما توفي رسول الله ﷺ
After the death of the Messenger of Allah ﷺ.
During the Prophet’s lifetime, revelation and his authoritative instruction resolved disputes. The later technical category of consensus therefore operates after his passing, when scholars must apply the revealed sources to new questions.
Furu al-din refers to practical and inferential legal matters. Foundational truths such as divine oneness and prophethood do not rest merely upon a later scholarly agreement; they have their own decisive sources. Consensus does not replace that foundational evidence.
