Meaning
Time is time after it has been specified by a known event. Thus, the definition does not present time as time in the absolute, but as time connected to a known event.
What Is Attributed to Shahrur
The cited passage attributed to the Book and the Qur’an contains a direct definition: “Time: linking time to a known event; that is, a specified or timed duration.”
The Atlas’s Explanation
The atlas understands from this definition that time is not time in its unrestricted sense, but time insofar as it is connected to a known event that specifies it. This is an explanation of the definition, not an independent definition of time. Nor does this mean that the two terms are synonymous in this context.
Synthetic Inference
This definition helps in reading the page Time in the Qur’anic Conception Is Relative and Constrained by the Event: at the minimum level established by this citation, what is meant by constraint is the connection of time to a known event. For reading in the broader context, see also History, Development, and Laws.
Open Question and Limits of the Evidence
The available citation does not explain what counts as a “known event” in every usage, nor does it by itself provide sufficient applied examples. The quotation is also preserved as documented evidence, but the surrounding raw text is unavailable in the evidence data; therefore, the discussion is limited to its explicit definitional import, without attributing a broader context to it.
