Assalamu Aleikum wa rahmatu lilahi wa barakatu

May Allah reward you with the highest ranks in this world and in the other for your strong efforts inshallah.

A) I have a question regarding stopping on a word ending with the letter "ya" first with a shadda and secondly without a shadda.  In surah al ahzab verse 56:
When stopping on the word Nabi (prophet), in the recitation of Hafs, I have heard while listening to the verse that the reader ends by saying "Nabiyy" (with a sukoon on the "ya") with a little emphasis since there is a shadda. However in surah al qiyamah verse 26, when stopping on the word " At taraqiya" (which does not have a shadda) instead of stopping with a sukoon on the "ya', the reader reads "taraaqii" with a 2 vowel count (please correct me if I am wrong).
Would you please explain this difference?
B) Although both styles of reading (what is commonly called mujawwad and murrattal styles) are read using the rules of tajweed:
1- Did the prophet Mohammed, peace be upon him, use to read in a mujawwad style in front of an audience (just like the qaris were/are doing in the masdjid)
2- Did either one or some of his (pbuh) sahabah used to do it?
3- If no, is this style (mujawwad) allowed or an innovation?
May Allah facilitate your answers inshallah.

Wa alaikum assalaam wa rahmatullahi wa barakatuh,

Jazakum Allahu khairan and may Allah reward you greatly.

A) When stopping on a word that has a shaddah on the last letter as in , it is necessary to put emphasis on this last letter to make clear that there is a shaddah, otherwise it will not be distinguishable from a letter without a shaddah.  This is called , or the accent.  To read more about  and its various circumstances, please see the following link: http://www.abouttajweed.com/new_page_7.htm .

A word without a shaddah on the last letter should be stopped on with a normal sukoon.  In the case of the word we would stop with a two count lengthening on the since we put an incidental sukoon on the  and it is preceded by a kasrah. 

B) Most of the reports state that the Prophet,  read the Qur’an in a slow measured reading, there were no names for the different speeds of reading then, there was no need for names.  The science of tajweed was written down and documented after Islam spread out into non-Arab lands and the tongue of the Arabs started corrupting.  The old books of tajweed list three allowable speeds of recitation 1) which is the slowest way of reading 2) an intermediate speed that is faster that the first one and 3)  a faster speed that the first two.  The first level,  in more modern books sometimes is called al-marattil and much less common is the term mujawwad.  Al-mujawwad actually means reading with tajweed which should be done at any speed we read at.  Al-Murattil refers to the aayah,  which most scholars of tajweed say means read the Qur’an with tajweed in a measured manner, which we all should do no matter which speed we are reading.   The early scholars of tajweed put down in writing these three levels of reading based on authentic chains of reading passed down to them from the earlier generations going back authentically to the companion and the Prophet, .  We can therefore feel confident that these three different levels of reading are from the authentic recitation of the Qur'an.   Jazakum Allah khairan.  Wa assalaam alaikum wa rahmatullah.
