Question
Asalam aleykum.
I have noticed
that the recitation of warsh an naafi' has a lot of ahkaam of hamza.
Could you please tell me about ahkam hamza of riwayat warsh
jazakumulaahu. wasalam aleykum
Answer
Wa alaikum
assalaam wa rahmatu Allahi wa barakatuh.
There are sets
of rules and sometimes two possible ways of recitation for different
occurrences of the hamzah in the recitation of Warsh, too many to lay out in a
question and answer. We do plan to
put the rules of Warsh and the other recitations up on the site, but cannot do
it at this time.
We will give
you the two most commonly encountered rules, and when Allah permits, the
complete set of rules will be put up.
The
Single Hamzah 
Warsh
changes (makes
of) the
hamzah saakinah that is the first letter of the root of the word into a medd
letter corresponding to the vowel on the letter preceding the hamzah.
This requires enough knowledge
of the Arabic language to derive a noun or conjugated verb into its root.
The word
has
a hamzah saakinah. The root of
this word is
,
with a hamzah as its first letter. Warsh
therefore changes the hamzah saakinah in the word
into
a lengthened
(two
vowel counts), and reads it as: 
.
All other words that have a hamzah saakinah which is the first letter
of the root form of the verb will be read in the same way, with the hamzah
saakinah changed into a corresponding medd letter.
Exception:
If the word in
question comes from
then
there is no
for
Warsh, such as in the words:
,
,
and
.
Again, these last three words are read with a regular hamzah saakinah
and there is no changing of the hamzah into a medd letter.
Warsh also
changes the hamzah with a
preceded
by a dhammah into a
(with
a
)
as in:
,
,
and
.
These words then are read without a hamzah but instead with the letter
with
a
.
An example is that the word
is
read as
in
the recitation of Warsh.
The three
words:
,
,
and 
are
read with
of
the hamzah into a
saakinah
in the recitation of Warsh.
Transferring the vowel on the
hamzah to the preceding saakin letter 
When the last
letter of a word is not a medd letter and is saakin, and the first letter of
the next word is a
,
Warsh transfers the vowel of the hamzah to the saakin letter before it,
and the hamzah is dropped in pronunciation. Examples of this are:
, 
,
and
.
Included in
this rule is the
or
alif laam at-ta’reef, which is a different word than the noun it defines.
Examples are:
,
,
and
, which would be read as:
,
,
and
. The
hamzah as stated before is dropped in pronunciation in these cases.
Wa
iyyakum. Wa
assalaam alaikum wa rahmatu Allah.
