Discussing worldly matters in the mosque and its effect on the reward

Question:
He says: Honorable Shaykh, may Allah grant you success, is there a hadith from the Sunnah indicating that speaking in the mosque about worldly matters reduces the reward?

Answer:
Yes, yes, it has been reported. As for a little, asking one easy question or a little talk, it does no harm, because this is the custom, it does not take up time, and it does no harm. But if every time you sit in the mosque, all your talk is about worldly matters, buying and selling, then you have no reward; it takes your good deeds, and you have no reward for sitting in the mosque, and you are rude to the mosque. Yes.
