Throat-letter clarity

The mechanic

When a noon carrying sukun, or a tanween, is followed by one of the six throat letters ء ه ع ح غ خ, the noon is pronounced plainly with no nasal blending. In the KFGQPC text this is written with an explicit sukun on the noon, or with the two tanween marks set side by side.

صِرَٰطَ ٱلَّذِينَ أَنۡعَمۡتَ عَلَيۡهِمۡ غَيۡرِ ٱلۡمَغۡضُوبِ عَلَيۡهِمۡ وَلَا ٱلضَّآلِّينَ
