How many makhraj are there in Hafs?

How many makhraj are there in Hafs?

The number of makhaaraj, or articulation points of letters does not change from one of the qira'aat to another.  The letters are pronounced from the same articulation point.
 Imam Ibn Al-Jazaree (died 833 h) stated that most of the scholars of tajweed assigned 17 articulation points to the letters.  This is the widely accepted number.  There were some scholars who gave 16 and others who gave 14, but basically they are the same and there is no difference in pronunciation. 
Again, the accepted number is that given by Imam Ibn Al-Jazaree, may Allah be merciful to him, 17.
