I got this site address few days ago, alhamdulillah, and I started reading everything because I found this site very interesting and helpful.
For a long time I've been thinking 'bout mistakes while the recitation and on your site, in the chapter "Common Tajweed Mistakes" I found an information, that:
"Some mistakenly use the throat, like the French do in the French "r"."
I'm not French but when I was born, i got a surgery because my tongue was mine rooted to the palate. The effect of it is, that I can't pronounce any other "R" sound than the French one, though I was working with my speech therapist all along.
I realize that this question can seem a bit strange, but I would like to ask, what should I do, if I got a speech impediment like this? Is it some kind of mistake?
Wa alaikum assalaam wa rahmatullahi wa barakatuh.
May Allah increase you in beneficial knowledge. This is not at all a strange question, but it seems to be one from a sincere student of the Qur'an. Allah knows best.
Allah does not charge a soul except [within] its capacity.
This is not something you can control and you will not be held accountable for that, insha’ Allah. The only thing that would affect you is if reached a high level in tajweed knowledge and application and you had students. You would need to bring another teacher in to teach the letter , and would have to be able correct the students if they had a mistake in the , even though you cannot pronounce it correctly.
May Allah make easy for you all khair.
Wa assalaam alaikum
