It is narrated from Sayyiduna Ibn Abbas (may Allah be pleased with them both) that once, at midday, I had the honor of seeing the Prophet (peace and blessings be upon him) in a dream. At that time, the Prophet’s (peace be upon him) hair was disheveled and there was dust on his body. He (peace be upon him) had a bottle with him in which he was searching for something. I asked,“O Messenger of Allah! What is this?”He replied,“This is the blood of Husayn and his companions. I have been collecting it since morning.”The narrator of the hadith, Ammar, says that we remembered that date in our minds, and later it became known that Sayyiduna Imam Husayn (may Allah be pleased with him) was martyred on that very date and day (on which Sayyiduna Ibn Abbas, may Allah be pleased with them both, saw the dream).
