Do not supplicate against yourselves, do not supplicate against your children, and do not supplicate against your property, lest you do it at a time in which Allah answers all supplications so you will be granted what you asked for

Explanation

In this Hadīth, the Messenger of Allah (may Allah’s peace and blessings be upon him) warns of supplicating against one’s children and property, because supplication is a serious matter, and Allah may answer it if it is made in an hour when all prayers are answered. Hence, it would actually harm the person who made the supplication and his children and property.
