Sitting in gatherings that contain sins and the ruling on singing

The questioner:
Also, Shaykh, some public gatherings are characterized by certain sins and backbiting, like gatherings of no benefit. Should a person stay, or is it obligatory for him to be among the people of good?

The Shaykh:
In any case, if you are giving advice and forbidding what is wrong, do not sit with them. But if you remain silent and do not forbid them or disapprove of them, do not sit with them, unless there is a need to be present with them or they are in need of you. This falls under the category of maintaining family ties.

The questioner:
And you have that too.

The Shaykh:
It is one thing, and this must be included in it: the accounts of the Ajadi, the accounts of the Krawawi, and the accounts of the Jama'ah, including the Sufis among them. But this is not correct; this is a wrong fatwa, and it is not permissible to act upon it, because singing is forbidden, including the diversion of hearts from the remembrance of Allah the Exalted, as messengers. A group of the Companions interpreted "idle talk" as singing, and Ibn Mas'ud swore three times that it is singing. Yes.
