Sayyiduna Anas bin Malik (may Allah be pleased with him) narrates from Sayyiduna Abu Talhah (may Allah be pleased with him) that when the Messenger of Allah (peace and blessings be upon him) attacked Khaybar early in the morning, he recited this verse: "Indeed, when We descend upon the courtyard of a people, evil is the morning of those who were warned" [Surah al-Saffat: 177].
