Is there any Sharia-related reservation in saying: "Whoever thinks that life will stop for anyone, let him seek refuge in Allah; the Prophet (peace and blessings of Allah be upon him) died, and the conquests continued"?

A Muslim must observe propriety in their discourse. The statement, "Whoever thinks that life will stop for anyone should seek refuge in Allah," is seemingly correct, for life does not stop for people. However, if the statement, "The Prophet (peace be upon him) died, and then there were conquests," is intended to disparage the prophetic status or belittle the message, then this is a grave error, even disbelief, because the presence of the Prophet (peace be upon him) was a source of security for the Ummah. But if it is meant to convey that Allah's laws are ongoing and do not cease with anyone's death, even prophets, then this meaning is correct. Nevertheless, it is impermissible to use ambiguous or misleading phrases to convey a correct meaning.
