My problem is that I find difficulty in pronouncing some letters. Is there an Islamic treatment for this (Ruqyah) or any other psychological treatment? The reason for this problem is that my mother beat me severely when I was five, and from then on I have suffered from it.

All perfect praise be to Allaah, the Lord of the worlds. I testify that there is none worthy of worship except Allaah, and that Muhammad, sallallaahu ‘alayhi wa sallam, is His Slave and Messenger.

We ask Allaah the Almighty to cure and treat you. You should know that Allaah the Almighty is the Curer so you must sincerely resort to him. We advise you to combine two types of treatment: treatment with Sharee`ah Ruqyah and treatment with Quranic supplications and remembrances. The Quran is a treatment for all physical and psychological diseases. Additionally, it is better if you make Ruqyah for yourself, but if not, then others can perform it for you.  You can also pursue medical treatment by going to specialized physicians.

You should also know that Allaah the Almighty tests His slaves to distinguish those who are patient from those who are discontent: those who are patient will have the reward of patience and the discontent will have the punishment of discontentment. Be patient and seek reward only from Allaah the Almighty!

As for your mother, beware of responding to Satan's call to be undutiful to her or to be less caring or to feel hate for her. She probably did this only because she thought that it would discipline and benefit you. Ask Allaah the Almighty to forgive her and try hard to be dutiful to her and this may speed your recovery. Do not forget to ask her to supplicate for your recovery, as the parents’ supplications are answered.

Allaah Knows best.
