Sahih Bukhari Volume 9, Book 91, Hadith 7004

قَالَتْ فَقُلْتُ مَا يُضْحِكُكَ يَا رَسُولَ اللَّهِ قَالَ ‏"‏ نَاسٌ مِنْ أُمَّتِي عُرِضُوا عَلَىَّ، غُزَاةً فِي سَبِيلِ اللَّهِ، يَرْكَبُونَ ثَبَجَ هَذَا الْبَحْرِ، مُلُوكًا عَلَى الأَسِرَّةِ أَوْ مِثْلَ الْمُلُوكِ عَلَى الأَسِرَّةِ ‏"‏‏.‏ شَكَّ إِسْحَاقُ‏.‏ قَالَتْ فَقُلْتُ يَا رَسُولَ اللَّهِ ادْعُ اللَّهَ أَنْ يَجْعَلَنِي مِنْهُمْ، فَدَعَا لَهَا رَسُولُ اللَّهِ صلى الله عليه وسلم ثُمَّ وَضَعَ رَأْسَهُ ثُمَّ اسْتَيْقَظَ وَهْوَ يَضْحَكُ‏.‏ فَقُلْتُ مَا يُضْحِكُكَ يَا رَسُولَ اللَّهِ قَالَ ‏"‏ نَاسٌ مِنْ أُمَّتِي عُرِضُوا عَلَىَّ، غُزَاةً فِي سَبِيلِ اللَّهِ ‏"‏‏.‏ كَمَا قَالَ فِي الأُولَى‏.‏ قَالَتْ فَقُلْتُ يَا رَسُولَ اللَّهِ ادْعُ اللَّهَ أَنْ يَجْعَلَنِي مِنْهُمْ‏.‏ قَالَ ‏"‏ أَنْتِ مِنَ الأَوَّلِينَ ‏"‏‏.‏ فَرَكِبَتِ الْبَحْرَ فِي زَمَانِ مُعَاوِيَةَ بْنِ أَبِي سُفْيَانَ فَصُرِعَتْ عَنْ دَابَّتِهَا حِينَ خَرَجَتْ مِنَ الْبَحْرِ، فَهَلَكَتْ‏.

Um Haram asked, "What makes you smile, O Allah's Apostle?" He said, "Some of my followers were presented before me in my dream as fighters in Allah's Cause, sailing in the middle of the seas like kings on the thrones or like kings sitting on their thrones." (The narrator Ishaq is not sure as to which expression was correct). Um Haram added, 'I said, "O Allah's Apostle! Invoke Allah, to make me one of them;" So Allah's Apostle invoked Allah for her and then laid his head down (and slept). Then he woke up smiling (again). (Um Haram added): I said, "What makes you smile, O Allah's Apostle?" He said, "Some people of my followers were presented before me (in a dream) as fighters in Allah's Cause." He said the same as he had said before. I said, "O Allah's Apostle! Invoke Allah to make me from them." He said, "You are among the first ones." Then Um Haram sailed over the sea during the Caliphate of Muawiya bin Abu Sufyan, and she fell down from her riding animal after coming ashore, and died.
