Explanation of the Expiation for the Assembly

Question:
This questioner asks, Shaykh, about the expiation for the assembly, and whether it is recited even after an assembly of dhikr, or is it specific to assemblies where there is a lot of idle talk?

Answer:
No, it is general. The expiation for the assembly is general for assemblies of good and assemblies where there is idle talk, some cursing, and the like. The closing of the assembly expiates what occurs in the assembly, and it is the expiation for the assembly: "Subhanaka Allahumma wa bihamdika, ashhadu an la ilaha illa anta, astaghfiruka wa atubu ilayk." If the assembly was an assembly of good, it is like a seal upon it, and if there was evil in it, it purifies it from that. Yes.
