Silsilah as-Sahihah 3733 — Prohibition of Sitting with Those

It is narrated from Sayyiduna Abdullah bin Mas'ud (may Allah be pleased with him) that the Messenger of Allah (peace and blessings of Allah be upon him) said: "Soon there will be people in the latter times who will sit in circles in the mosques, and their greatest concern will be the world. Do not sit with such people; Allah has no need of such people."
