If our prayer does not prevent us from shameful and unjust deeds, does it mean that the prayers we perform will not be accepted?

Dear Brother / Sister,

When a person performs the fards of the prayer, it will be valid and his/her mistakes/sins do not invalidate his/her prayer.

This one and similar expressions in the Qur'an and hadiths are used in order to define the perfect prayer. That is, if a person performs his/her prayers perfectly, it will prevent him/her from mischief.

As the perfectness of the prayer lessens, its protection from evilness weakens.
