Assalam-U-Alikum!!!
I knw few Tajweed rules which i hav learnd myself.
1=Ikhfa it will be pronounced with a light nasal sound.
2=Gunnah The sound emanantes from the nose and is observed on the NooN & MeeM
3=Ikhfa Meem Sakin when the lettr Ba appears aftr a Meem it will be Pronunced with a light sound in the nose.
4=Idgham If aftr a NooN //(Fatah)-----------------------"(Dama) there appear anyof -----------------------------//(Kasra) these letters (Wao,Meem,Noon,Ya) it will become assimilated into the lettr and will be read with Ghunna
5=Iqlab If after a Noon or //(Fatah)-----------------------"(Dama) the lettr Ba ----------------------------------//(kasra) appears then the Noon saakin or Tanween will be incorporated into the letter Meem and will be recited with Ghunna.
6=Qalqala
the five letters of Qalqala are (daal,Jeem,Ba,Tua,Qaaf) when any of these letters in a word has a sukoon on it or if deciding on pausing on any of these letters which appear at the end of a sentence it will appear to have an echoing or jerking sound.
7=Idghaam Meem saakin if aftr a Meem there appear another Meem the two meems will become incorporated and will be read with Ghunna.
