Question: Is it from the guidance of the Prophet (ﷺ) to give a general advice to the people in the situation of a wedding?
Answer: “I do not know of anything in that, however, a person speaking with advice in a situation when people gather and him mentioning good to them, then there is no harm in it.
There is nothing preventing him from that however, it is not said: verily this is Sunnah. However it is from the palatable affairs in which the people are reminded when there is a need for that”.
