Is it permissible for us to attend condolence gatherings in order to invite some of the Sufis whom we do not meet except in those places?

Question:
Honorable Shaykh, may Allah grant you success. The questioner says: We have some Sufis who are fanatical and far from the gatherings of knowledge, so they do not know tawhid (the oneness of Allah) or the Sunnah, but rather they fall into shirk (associating partners with Allah) and bid'ah (religious innovations). These people attend condolence gatherings, and we cannot meet them except in this place. His question is: Can we explain tawhid and the Sunnah to them in this place, the place of condolence, out of necessity? Knowing that some of them have come to know the truth and been guided to it in this place?

Answer:
First, condolence does not have a specific place or gathering. Condolence does not require a place or a gathering. Condolence consists of words and supplications said to the bereaved, such as "May Allah improve your consolation, may Allah heal your affliction, and may Allah forgive your deceased," in any place: in the mosque, in the shop, in the market, or in a phone call, spoken face-to-face. This is condolence. As for the Sufis, if the opportunity presents itself to you in the condolence gathering or in other places—whether in the condolence gathering you mentioned or elsewhere—and the opportunity presents itself, then call to Allah and explain. And you are doing good, if Allah wills. Yes.
