[DINAKuncher]

Im currently taking a tajwid course in my city. and alhumdulillah its very beneficial and im so grateful that Allah Ta'ala gave me the tawfeeq to learn tajweed. Tajweed is BEAUTIFUL! subhanAllah.

It is so important to pronounce the letter ض from its proper makhraj or else we cud be making grave errors in recitation.

the makhraj of ض is haffatul lisaan... the back side of the tongue should touch the top right molars or top left or both sides.

here is an illustration: http://www.iqrapk.com/tajweed/2.htm

if u practice this, (and its best done with a qualified teacher) you will notice the difference in the pronounciation of ض and daal and dhaa.

the daal is pronounced from ... the tip of the tongue touching the top front teeth. so it is distinct from Dhaad.

also learning the charcteristics (sifaat) of all the letters will help one distinguish the points of articulations and special charcteristics of each letter. For example, the letter Dhaad is a letter of isti' la (rough letter) while daal is a letter of istifaal (soft letter).

may Allah give us all the tawfeeq to learn and recite the Quran with tajweed. ameen
