The Prophet ﷺ said, "Last night two men came to me (in a dream) and made me ascend a tree and then admitted me into a better and superior house, better of which I have never seen. One of them said, 'This house is the house of martyrs."
قَالَ النَّبِيُّ ﷺ رَأَيْتُ اللَّيْلَةَ رَجُلَيْنِ أَتَيَانِي فَصَعِدَا بِي الشَّجَرَةَ فَأَدْخَلاَنِي دَارًا هِيَ أَحْسَنُ وَأَفْضَلُ لَمْ أَرَ قَطُّ أَحْسَنَ مِنْهَا قَالاَ أَمَّا هَذِهِ الدَّارُ فَدَارُ الشُّهَدَاءِ
[Machine] The translation of the given Arabic text is as follows:
"When the Messenger of Allah ﷺ prayed the Fajr prayer, he would turn toward us with his face and say, 'Did anyone among you see a dream last night?' So, one day we asked him (about the dreams), and he said, 'I saw two men coming to me and holding my hand, then they took me and ascended with me in a tree. They entered a house with me, which I had never seen anything better than. Then he said, 'This house is the house of martyrs'."
كَانَ رَسُولُ اللَّهِ ﷺ إِذَا صَلَّى الْغَدَاةَ أَقْبَلَ عَلَيْنَا بِوَجْهِهِ فَقَالَ «هَلْ رَأَى أَحَدٌ مِنْكُمُ اللَّيْلَةَ رُؤْيَا؟ » فَسَأَلْنَا يَوْمًا ثُمَّ قَالَ «أُرِيتُ اللَّيْلَةَ رَجُلَيْنِ أَتَيَانِي فَأَخَذَا بِيَدِي فَصَعِدَا بِي فِي الشَّجَرَةِ فَأَدْخَلَانِي دَارًا لَمْ أَرَ قَطُّ أَحْسَنَ مِنْهَا فَقَالَ أَمَا هَذِهِ الدَّارُ فَدَارُ الشُّهَدَاءِ»
