It is narrated from the Mother of the Believers, Sayyidah Aishah (may Allah be pleased with her), that she said: "The Prophet (peace and blessings be upon him) came to one of the gathering places of the Ansar, where a group of them were present. He (peace and blessings be upon him) greeted them with salam and they returned the greeting, but the Prophet (peace and blessings be upon him) disliked for them that gathering place. They said: 'O Messenger of Allah! This is a gathering place where our forefathers used to sit in the time of Ignorance (Jahiliyyah), so we liked to keep it alive and sit here.' He (peace and blessings be upon him) said: 'If you will not refrain (from sitting there) and must do it, then return the greeting of salam, lower your gazes, and show the way (to travellers).'"
No one narrated this hadith from Mansur except Salih bin Musa al-Talhi (may Allah have mercy on him).
