Explanation of the saying of Ibn Malik (may Allah have mercy on him): "And every time is capable of that, and what the place accepts is only indefinite."

The Shaykh : All right, he said: "And every time is capable of that" meaning: every time. The term "time" here refers to duration. Every duration is capable of being a locative of time (ma'ful fih). Every duration, unlike place. Duration is an hour, a minute, a second, a day, a week, a month, a year, a moment, an era, and the like. Every duration is capable of being a locative of time, or is it not? All right, this is the rule. So, all duration is capable of being a locative of time, because there is nothing that is not in a duration. There is nothing that is not in a duration. You say, "Wait for me a second." What is the grammatical case of "second"?
The student: An adverb.

The Shaykh : It is a locative of time, or you can say: a temporal adverb, in the accusative case due to being a temporal adverb. "Wait for me an hour"? The same thing. But know that the "hour" in the Arabic language is different from it in common usage. In our common usage, the hour is one of twenty-four parts of the day and night. But in the Arabic language, it is used for duration, whether little or much, for duration whether little or much. All right, every time, meaning every duration, is capable of being in the accusative case due to being a temporal adverb. But place is not. "And what the place accepts is only indefinite". The specific, such as a room, a chamber, a house, and the like, this does not accept being a locative of time unless it is indefinite. Indefinite means: not limited, not specified, that which has nothing to specify it.
