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 Messenger of Allah 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 Messenger of Allah 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 Messenger of Allah 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. (Using translation from Bukhārī 2894)
أَنَّ النَّبِيَّ ﷺ قَالَ يَوْمًا فِي بَيْتِهَا فَاسْتَيْقَظَ وَهُوَ يَضْحَكُ فَقَالَتْ يَا رَسُولَ اللهِ مَا يُضْحِكُكَ؟ قَالَ «عَجِبْتُ مِنْ قَوْمٍ مِنْ أُمَّتِي يَرْكَبُونَ الْبَحْرَ كَالْمُلُوكِ عَلَى الْأَسِرَّةِ» قَالَتْ فَقُلْتُ يَا رَسُولَ اللهِ ادْعُ اللهَ أَنْ يَجْعَلَنِي مِنْهُمْ قَالَ «أَنْتِ مِنْهُمْ» ثُمَّ نَامَ فَاسْتَيْقَظَ وَهُوَ يَضْحَكُ فَقَالَ لِي مِثْلَ ذَلِكَ مَرَّتَيْنِ أَوْ ثَلَاثًا وَأَقُولُ يَا رَسُولَ اللهِ ادْعُ اللهَ أَنْ يَجْعَلَنِي مِنْهُمْ فَيَقُولُ «أَنْتِ مِنَ الْأَوَّلِينِ» قَالَ فَتَزَوَّجَهَا عُبَادَةُ بْنُ الصَّامِتِ فَخَرَجَ بِهَا إِلَى الْغَزْوِ قَالَ فَلَمَّا رَجَعَتْ قُرِّبَتْ لَهَا دَابَّةٌ لِتَرْكَبَهَا فَوَقَعَتْ فَانْدَقَّتْ عُنُقُهَا
