My favorite dua is Prophet Musa (AS) dua which is 'Rabbi shrahli sadri wa yasirli amri wahlul ukhdatam milisaani yafkahu qawli'. As I child I learnt this dua listening to people recite it before an islamic speech or talk. My mother, one day, taught me the meaning of it as she explained that Musa (AS) used to stammer and that in the dua . he asks Allah to 'loosen the knot of his tongue'. I was deeply moved by this knowledge. It touched a chord with me because though I was painfully shy, I loved participating in public speaking. I always remembered to say this dua before speaking in front of a group of people. I believe, Alhamdulillah, that the prayer had helped me quell the jitters on particularly nervous occasions. The significance of this dua in my life came back to me years later when my first born, my daughter was 2 years old. A talkative child from since she was not yet one, Zainab spoke clearly and confidently and was comparable to a much older child in her phrases and choice of words. Then one day, to our horror, she suddenly began to stammer. I tried to dismiss it as a phase she was going through at first but it kept getting worse with each passing day. It reached a stage when she wasn't able to get a single sentence out without struggling. It was heart breaking because she kept asking me 'Mamma, what has happened to my voice?'. We began speech therapy which lasted around 6 months. Throughout this period, every single day I prayed to Allah for strength and wisdom to see the purpose of this trial. I recited my favorite dua with an intensity and fervor like never before. I taught the dua to Zainab and we recited it together everyday. Alhamdulillah, with Allah's Grace and Mercy Zainab was fine by the end of the year, though changed. She didn't race through her words like before, rather she spoke carefully and slowly, gathering her thoughts as she spoke. We, as parents were changed too. The therapy taught us to listen to our children more patiently, to stop whatever we were doing and give them the attention they asked for when they really needed it. It taught us to be careful with our words and facial expressions because children can catch those hints and it affects them. Alhamdulillah, every trial has a purpose and our faith showed us that purpose. I now understand what is meant by the power of dua.
