The information on this website has been much appreciated. May Allah give you the ability to keep up the work inshallah.
1. I wanted to know, regarding idghaam naaqis specifically (of yaa and waw), how much of it comes from the nose and how much from the mouth. One of my teachers said that idghaam is completely from the nose. Such that if you were to pinch your nose and say an idghaam with yaa or waw, you will not be able to. I have not heard any reciter's do idghaam like this. Is the sound meant to be half from the mouth and half from the nose, more from the nose then the mouth or completely from the nose? If possible, could you refer to any tajweed books that give this answer also and state if there is any difference of opinion regarding this.
2. Could you also do the same for ikhfa. i.e. what is the ratio of the ghunna and does the amount of ghunna change depending on the following letter and if so by how much.
3. Also, I know there are different levels of strength for the full mouth letters but I haven't come across where the letter raa is. Is it weaker then all the permanently full mouth letters and does it also follow the rule of strongest with a fatha and then dhamma?
4. Finally, when it comes to qalqalah. There are 2 levels. Are the levels something we need to try and achieve or are they meant to come naturally i.e. a qalqalah in the middle of a word, would we need to try to make that less then one at the end or is that meant to happen naturally?
Wa alaikum assalaam wa rahmatullahi wa barakatuh.
Ameen to your dua', may Allah accept it from us.
1. The general amount for the idghaam naaqis of the noon as-saakinah and at-tanween into the ya' and wow, although it is not a hard and fast rule, is 50% ghunnah and 50% of the articulation rule. This is an approximation, but often used as a guideline.
2. In the ikhfa', the general amount, and again it is not a solid rule is 75% ghunnah and 25% of the sound produced when hiding the noon saakinah and getting the mouth ready to pronounce the next letter.
3. The letters such as the ra' and laam which sometimes have tafkheem and sometimes have tarqeeq do not have levels of tafkheem, instead they either have tafkheem or they don't. The tafkheem is a strong tafkheem, but all ra' aat and laamaat which have tafkheem have one level of tafkheem.
4. It is a natural occurrence that the qalqalah al-kubraa is stronger because it is the last letter we read and we are not joining it with a word after that so we do not need to try and make it stronger.
