Mishkat al-Masabih 30 Fine Qualities كتاب المناقب 181

وَعَنْ سَلْمَى قَالَتْ: دَخَلْتُ عَلَى أُمِّ سَلَمَةَ وَهِي تبْكي فَقلت: مَا بيكيك؟ قَالَتْ: رَأَيْتُ رَسُولَ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ – تَعْنِي فِي الْمَنَامِ – وَعَلَى رَأْسِهِ وَلِحْيَتِهِ التُّرَابُ فَقُلْتُ: مَا لَكَ يَا رَسُولَ اللَّهِ؟ قَالَ: «شَهِدْتُ قَتْلَ الْحُسَيْنِ آنِفًا» رَوَاهُ التِّرْمِذِيُّ وَقَالَ: هَذَا حَدِيثٌ غَرِيبٌ

Salma said: I went in to visit Umm Salama and found her weeping. I asked her what was making her weep and she replied that she had seen God’s messenger (meaning in a dream) with dust on his head and beard. She asked him what was the matter and he replied, “I have just been present at the slaying of al-Husain.” Tirmidhi transmitted it, saying this is a gharib tradition.
