عن أبي هريرة رضي الله عنه أنه سمع رسول الله صلى الله عليه وسلم يقول‏:‏ ‏"‏من سمع رجلا ينشد ضالة في المسجد فليقل‏:‏ لا ردها الله عليك، فإن المساجد لم تبنَ لهذا‏"‏ ‏(‏‏(‏رواه مسلم‏)‏‏)‏‏.‏

'Amr bin Shu'aib on the authority of his grandfather (May Allah be pleased with him) said

The Messenger of Allah (ﷺ) prohibited (us) from buying and selling in the mosque; (he also prohibited us from) making announcement in it about something lost and from reciting poems in it.[Abu Dawud and At- Tirmidhi].
