The ruling on supplication after a lecture or sermon

Question:
He says: Sometimes, after delivering a lecture or a lesson, the lecturer makes supplication and raises his hands. Should we sit with him during the collective supplication, or should we leave after the lecture before the supplication begins? Please issue a ruling for us, may Allah reward you.

Answer:
There is nothing wrong with making supplication after a lecture, or after a sermon and reminder; there is nothing wrong with making supplication, asking Allah for success and guidance for those present, and for the rectification of intention and deeds. However, regarding raising the hands in such a case, I do not know of any evidence for it, and I do not know that it was reported from the Prophet (peace and blessings be upon him) except in general terms, the general practice of raising hands in supplication, and that it is one of the causes of acceptance. But I have not memorized from him (peace and blessings be upon him) that he used to raise his hands and make supplication after he would admonish the people and remind them. If he had done this, the Companions (may Allah be pleased with them) would have reported it, for they did not leave anything unreported (may Allah be pleased with them).
Therefore, the better and more cautious course is not to raise the hands in such a case, unless one finds evidence indicating that. As for making supplication for them after he finishes, saying: “May Allah forgive us and you,” or “May Allah grant us and you success,” or “May Allah benefit us and you with what we heard,” or something similar to this; there is nothing wrong with that. And if they say “Ameen,” there is nothing wrong with that. Yes.

The presenter: May Allah reward you with good.
