Silsilah as-Sahihah 3738 — Blessed Friday and Its Black Spot

It is narrated from Sayyiduna Anas bin Malik, may Allah be pleased with him, that the Messenger of Allah, peace and blessings be upon him, said: "The days were presented to me (in their specific forms), among them was the day of Friday, which was like a white glass, and in its middle was a black dot. I said: What is this? It was said to me: This is the Day of Resurrection."
