When anyone of you prays, let him do so behind a barrier, even if an arrow

Explanation of the hadith

The Hadīth points out that it is recommended for a person to put something before him as a barrier when he offers prayer. That barrier can be anything he sets up in front of him, even if it were short or thin like an arrow. Indeed, this is one of the manifestations of the ease and leniency of the Islamic Shariah.
