Musannaf Ibn Abi Shaybah 39665 — The Battle of Khaybar

It is narrated from Sayyiduna Abu Hurayrah (may Allah be pleased with him) that the Prophet of Allah (peace and blessings be upon him) said: "Today I shall place the banner in the hand of a man whom Allah and His Messenger love." Upon this the people began raising themselves up to look. He (peace and blessings be upon him) said: "Where is Ali (may Allah be pleased with him)?" The people said: "He has a complaint in his eye." He (peace and blessings be upon him) called Sayyiduna Ali (may Allah be pleased with him), and he (peace and blessings be upon him) spat on both his palms and passed them over the eye of Sayyiduna Ali (may Allah be pleased with him). Then he (peace and blessings be upon him) handed the banner to Sayyiduna Ali (may Allah be pleased with him). And on that very day Allah Almighty granted victory at the hand of Sayyiduna Ali (may Allah be pleased with him).
