Sahih al-Bukhari 2894, 2895
Narrated Anas bin Malik:
Um Haram told me that the Prophet (ﷺ) one day took a midday nap in her house. Then he woke up 
smiling. Um Haram asked, "O Allah's Messenger (ﷺ)! What makes you smile?" He replied "I was astonished 
to see (in my dream) some people amongst my followers on a sea-voyage looking like kings on the 
thrones." She said, "O Allah's Messenger (ﷺ)! Invoke Allah to make me one of them." He replied, "You are 
amongst them." He slept again and then woke up smiling and said the same as before twice or thrice. 
And she said, "O Allah's Messenger (ﷺ)! Invoke Allah to make me one of them." And he said, "You are 
amongst the first batch." 'Ubada bin As-Samit married her (i.e. Um Haram) and then he took her for 
Jihad. When she returned, an animal was presented to her to ride, but she fell down and her neck was 
broken.
حَدَّثَنَا أَبُو النُّعْمَانِ، حَدَّثَنَا حَمَّادُ بْنُ زَيْدٍ، عَنْ يَحْيَى، عَنْ مُحَمَّدِ بْنِ يَحْيَى بْنِ حَبَّانَ، عَنْ أَنَسِ بْنِ مَالِكٍ ـ رضى الله عنه ـ قَالَ حَدَّثَتْنِي أُمُّ حَرَامٍ، أَنَّ النَّبِيَّ صلى الله عليه وسلم قَالَ يَوْمًا فِي بَيْتِهَا، فَاسْتَيْقَظَ وَهْوَ يَضْحَكُ، قَالَتْ يَا رَسُولَ اللَّهِ، مَا يُضْحِكُكَ قَالَ ‏"‏ عَجِبْتُ مِنْ قَوْمٍ مِنْ أُمَّتِي يَرْكَبُونَ الْبَحْرَ، كَالْمُلُوكِ عَلَى الأَسِرَّةِ ‏"‏‏.‏ فَقُلْتُ يَا رَسُولَ اللَّهِ، ادْعُ اللَّهَ أَنْ يَجْعَلَنِي مِنْهُمْ‏.‏ فَقَالَ ‏"‏ أَنْتِ مَعَهُمْ ‏"‏‏.‏ ثُمَّ نَامَ، فَاسْتَيْقَظَ وَهْوَ يَضْحَكُ فَقَالَ مِثْلَ ذَلِكَ مَرَّتَيْنِ أَوْ ثَلاَثًا‏.‏ قُلْتُ يَا رَسُولَ اللَّهِ، ادْعُ اللَّهَ أَنْ يَجْعَلَنِي مِنْهُمْ‏.‏ فَيَقُولُ ‏"‏ أَنْتِ مِنَ الأَوَّلِينَ ‏"‏ فَتَزَوَّجَ بِهَا عُبَادَةُ بْنُ الصَّامِتِ، فَخَرَجَ بِهَا إِلَى الْغَزْوِ، فَلَمَّا رَجَعَتْ قُرِّبَتْ دَابَّةٌ لِتَرْكَبَهَا، فَوَقَعَتْ فَانْدَقَّتْ عُنُقُهَا‏.‏
