It has been related that
would
stop gently without breathing while in the state of continuing his recitation
in four places of the revelation. It is required (waajib) for the
reader reciting the Qur'an by the way of Hafs 'an 'Aasim min tareeq Ash-Shatibiyyah
to do all of these
as
long as he/she is reading the two words that have a
in
between them in continuum. If the reader stops between the two words (which
is allowed in al-Kahf and Ya seen), then the
would
not be employed, since it is now a stop.
All of these saktaat of Hafs are transmitted
by a sound chain of transmission from the Prophet,
. They are often referred to as the
saktaat of Hafs because they are unique to the way of recitation made famous
by Imam Hafs.
1. The
first
,
which as defined is a short breathless stop, is made on the alif substituted
in place of the tanween in the word
,
at the beginning of surah al-Kahf, when joining the first aayah with the next
one
,
then would read
.
This doesn’t mean that it is not allowed to stop on the word
since it is
the end of an aayah. If one stops though, there would be no
.
2. There
is also a
after
the word
,
in aayah 52 of surah YaSeen
when the reader joins it with the next phrase
without stopping. It is allowed to stop on the word

then there obviously would be no

NOTE:
These four
are
required when reading these words in continuum with what follows, when
reciting by the Shatabiyyah way of Hafs.
There are two allowed (
)
sakt in two different places in the Qur’an. These two sakt are not specific
to the recitation of Hafs, but are allowed in the other ways of recitation
also. These "allowed" saktaat means there is more than one allowed way of
reading in these places.
1. The
first allowed
is
between the end of surah al-Anfaal, and the beginning of surah at-Tawbah
when joining the end
of al-Anfaal with the beginning of surah at-Tawbah.
The allowed
is
on the
of
the word
then the recitation continues
with
. Again, there are other
allowed ways of joining these two surahs.
2. The
second allowed
is
on the word
, in verse 28 of surah al-Haaqqah when
continuing with the next aayah
.
We previously studied that there is another allowed way of reading when
joining these two aayat, that is idghaam of the first saakinah letter
of the word
into the
voweled
of
the word
.
Both of theses two ways of joining these two aayat are allowable.

the Glorious Qur’an.
