Were the Companions accustomed to conversing in the mosque during the time of the Prophet, peace and blessings be upon him, and did Aqil ibn Abi Talib do so?

Mosques were built for the remembrance of Allah, the establishment of prayer, the recitation of the Quran, and the dissemination of knowledge, as Allah the Almighty said: "In houses which Allah has ordered to be raised and that His name be remembered therein." The Prophet, peace and blessings be upon him, forbade their use for urination or filth, and emphasized that they are for the remembrance of Allah, prayer, and the recitation of the Quran. The Companions would converse in the mosque after Fajr about matters of the pre-Islamic era (Jahiliyyah), but their conversation was about the remembrance of Allah and the blessings of Islam, not about worldly matters or idle talk. It was reported that Uqail used to sit in the mosque to inform people about Arab genealogies, which is a matter that does not deviate from the essence of the Companions' conversations.
