Assalam walekum brothers & sisters if from inside you are getting voice that your Namaz / Salah is not as per the requirements of Islam.
Please refer to below app which is amazing i have used myself and found very satisfying, the speed of imam is perfect its very clear.
I personally recommend Muslims around the world due to Covid-19 cannot goto Masjid can use this app.
I have no connection of any financial / legal with Namaz App, it just i used it and found worth writing a blog.
Jazakallah for reading
