Is it true that it will be Umar ibn al-Khattab in the grave who will ask the two angels: "Who is your Lord and what is your religion?"

We do not know the authenticity of the saying, "Every nation has a trustee, and the trustee of this nation is Omar ibn al-Khattab." Omar ibn al-Khattab possesses great stature and immense virtues, but this does not mean exaggerating his status and attributing to him a saying that was not stated by the Sharia. Information about the unseen is only received through revelation.
