The ruling on saying "Allah and His Messenger know best" after the death of the Prophet

Question:
Honorable Shaykh, is it permissible in our current time to say, when asked, "Allah and His Messenger know best," or should we say only "Allah knows best"? Since the Messenger (peace and blessings be upon him) has passed away, and that phrase is not said except during your lifetime?

Answer:
I do not know of anything that prevents saying "Allah and His Messenger know best" as it came in the hadith. This does not mean delegating knowledge to the Messenger after his death; rather, this refers to him before his death (peace be upon him). "Allah and His Messenger know best" applies if he is alive. Hmm? And He knows everything. Matters of this world, yes. Did you see Allah or not? This does not require sleep; this does not require a person—you know he is coming, he is coming, or say "I do not know." It does not require saying "Allah and His Messenger know best," meaning you elevate his status to this extent. This is an ordinary matter: is he coming or not, or I do not know. If you say "Allah and His Messenger know best," this is an indication of his status and that it is an important matter. Yes.
