What is the Ruling on Publicizing the Nikah?

Sheikh: Do you mean is it obligatory? Questioner: To make ishhar. Sheikh: Yes, because the Prophet ﷺ said: "Announce this marriage and beat the duff (tambourine) upon it." Another questioner: "And keep them in the masjids" Sheikh: No, "keep them in the masjids" is an addition that is not authentic.
