A common mistake some Muslims make while they're engaged in prayer is that they don't properly cover their awrah. For example, some men wear small sized shirts and while it may cover them while they're standing, their lower back becomes exposed when they go down into sajda/prostration, potentially exposing their awrah and potentially invalidating their prayer. So let's make an effort to properly cover ourselves when we engage in the salaah/namaz, in sha Allah!
