Muslim Manners

Narrated Ibn ‘Umar (may Allah be pleased with him):

The Prophet (may Allah’s peace be upon him) forbade that a man should be made to get up from his seat so that another might sit on it, but one should make room and spread out.

Ibn ‘Umar disliked that a man should get up from his seat and then somebody else sit at his place.
