Taqrir is tacit approval: an act occurs in the Prophet’s presence or knowledge, and in circumstances where clarification would be expected it is not disapproved. Under the proper conditions, such non-objection may carry legal significance.
For example, an action known to the Prophet ﷺ may be assessed in light of his informed response, or the absence of a prohibition on an occasion that called for clarification.
Not every silence is taqrir. Ignorance of the event, an unsuitable occasion, or incomplete reporting cannot simply be equated with legal permission. This also links to the preceding lesson’s discussion of clarification by context.
