Later wording that reinforces an existing meaning illustrates bayan al-taqrir. If it resolves uncertainty, the category is bayan al-tafsir; if a condition or exception changes the prior scope, it concerns bayan al-taghyir.
In appropriate circumstances, silence or other indicators may serve as bayan al-darurah. Removal of a previous ruling concerns bayan al-tabdil, associated with abrogation. A subsequent statement is not automatically an abrogation; each form requires its own conditions.
