Etiquettes of the Mosque
A person was causing a commotion in the mosque stating that he had lost such and such thing. When Hazrat Ubayy (ra) saw this he was displeased. The person said, “I have not uttered anything vile in the mosque.” Hazrat Ubayy (ra) replied, “Indeed that is true; however, it is against the etiquette of a mosque to announce any worldly possession.”
