Question

I have a question about the definition I have found for (the basic or natural medd).  It says: "it is the med that without which the letter cannot exist and it does not stop due to a hamzah or a sukoon".  What is meant here by "does not stop"?

Answer

The natural lengthening, is two vowel counts.  If there is a hamzah or a sukoon after a medd letter, then the medd is longer.  The medd stops, or the timing of the medd ends, when the reciter reaches the next letter, in this case a hamzah or any other letter that has a sukoon.  In other words, the extra lengthening that occurs because of the hamzah or sukoon extends the medd, so it is no longer a natural two vowel count lengthening, but now something longer, and this extra lengthening is caused by a hamzah or sukoon.
