To be very clear. I shared my experience with you to give you a message. Forget about my and yours religion. First of all we are here to get a cure and to understand our problem. I shared the story with you to make you understand that we are not alone. I shared my story about been working in a call center. To show you guys that nothing is Impossible. A person who stutters will never want to attend a call but still I managed somehow. So do not underestimate yourself. I know speech Therapy works but not for everyone and thats me. It didn't work for me. So after loosing hope I get to know about this Moses story but you know I have heard this story before but never focuses on this part. But after hearing this I was so shocked that I had to replay the part to get the surity that what i heared was right. I cross verify from Quran and finally extracted the dua for myself and for those who thinks this could help.
