Manner of Upholding the Etiquette of the Prophet’s (sa) Mosque
There are also narrations regarding the manner in which Hazrat Umar (ra) upheld the etiquette of the Prophet’s (sa) Mosque and the prayers. Hazrat Sa‘ibra bin Yazid narrates that he was standing in the mosque when someone threw a stone towards him. He turned and saw that it was Hazrat Umar (ra) bin al-Khattab. Hazrat Umar (ra) said, “Bring those two people to me.”
There were two people who had been talking loudly. So, they were taken to Hazrat Umar (ra), who said, “Who are you two”, or, “Where are you from?” They replied that they were residents of Ta‘if. Upon this, Hazrat Umar (ra) said, “Had you been residents of this city, I would have punished you for speaking so loudly in the mosque of the Holy Prophet (sa).”
