«إذا صلى أحدكم إلى شيء يستره من الناس فأراد أحد أن يجتاز بين يديه فليدفعه فإن أبى فليقاتله فإنما هو شيطان»
The Prophet (peace and blessings be upon him) said:
"When one of you prays facing something that screens him from people, and someone wants to pass in front of him, let him stop him; and if he refuses, let him deal with him firmly (pushing him to the point of fighting), for he is nothing but a devil."
