ثم الإجماع على أربعة أقسام
Consensus is divided into four forms.
1. The Companions explicitly agree on a ruling.
2. Some Companions state a ruling while the remainder do not object.
3. Later qualified jurists agree on a matter for which no earlier position of the predecessors is recorded.
4. Later qualified jurists agree upon one of several earlier positions.
The distinction is not merely chronological. The mode of agreement, the status of earlier opinions, and the strength of the resulting evidence all affect the category.
