"I entered upon Umm Salamah while she was crying, so I said: 'What causes you to cry?' She said: 'I saw the Messenger of Allah - that is, in a dream - and there was was dirt on his head and his beard. so I said: "What is wrong with you, O Messenger of Allah?" He said: 'I just witnessed the killing of Al-Husain.'" (Using translation from Tirmidhī 3771)
دَخَلْتُ عَلَى أُمِّ سَلَمَةَ وَهِيَ تَبْكِي فَقُلْتُ مَا يُبْكِيكِ؟ قَالَتْ رَأَيْتُ رَسُولَ اللَّهِ ﷺ فِي الْمَنَامِ يَبْكِي وَعَلَى رَأْسِهِ وَلِحْيَتِهِ التُّرَابُ فَقُلْتُ مَا لَكَ يَا رَسُولَ اللَّهِ؟ قَالَ «شَهِدْتُ قَتْلَ الْحُسَيْنِ آنِفًا» سكت عنه الذهبي في التلخيص
