I wrote a post about this subject a couple of years ago. Hopefully, you’ll find this video a good supplement to that article, Inshallah.
Basically, when we pray, make the Salaah, we have to focus on Allah and make sure our motions, actions, and speech are devoted towards the remembrance of Allah. But it’s hard to do that if we don’t know what were saying.
The purpose of this video is to encourage everyone to learn what they’re saying in prayer, and use it as a means to focus and improve their concentration. Inshallah.
