[Machine] I saw the Prophet ﷺ one day during midday, with disheveled hair and a dusty face. He had a bottle in his hand containing blood. I asked him, "O Messenger of Allah, what is this?" He said, "This is the blood of Al-Hussein and his companions. I have been collecting it since that day." This was verified and it was found that they were killed on that day.
رَأَيْتُ النَّبِيَّ ﷺ فِيمَا يَرَى النَّائِمُ ذَاتَ يَوْمٍ نِصْفَ النَّهَارِ أَشْعَثَ أَغْبَرَ فِي يَدِهِ قَارُورَةٌ فِيهَا دَمٌ فَقُلْتُ بِأَبِي أَنْتَ وَأُمِّي يَا رَسُولَ اللهِ مَا هَذِهِ؟ قَالَ «هَذَا دَمُ الْحُسَيْنِ وَأَصْحَابِهِ لَمْ أَزَلْ أَلْتَقِطُهُ مُنْذُ الْيَوْمِ» فَأُحْصِيَ ذَلِكَ فَوُجِدَ قُتِلَ ذَلِكَ الْيَوْمَ
