Warding off the insinuating whispers of the Shaytaan

Push away the worldly
thoughts that come to you whilst praying as much as you can, and listen
to the imaam’s recitation and ponder the meanings of what he is reciting,
so that you may benefit from it, avoid letting your thoughts wander
and ward off the insinuating whispers of the Shaytaan. Recite al-Faatihah
in both the silent and loud prayers (where the recitation is done silently
or out loud), and recite another soorah or passage of  the Qur’aan
in the silent prayer, focusing on the meaning of the words. Perhaps
by this means Allaah will help you to focus your mind and overcome this
lack of concentration. It is also prescribed for you to seek refuge
with Allaah from the accursed Shaytaan when you face too many insinuating
whispers.

 And
Allaah is the source of strength. May Allaah bless our Prophet Muhammad
and his family and companions, and grant them peace.
