باب فَضْلِ الْغَزْوِ فِي الْبَحْرِ ‏‏
Sahih Muslim 1912 c

It has been reported on the authority of Umm Haram daughter of Milhan (through another chain of transmitters). She said:

One day the Messenger of Allah (ﷺ) slept (at a place) near me. He woke up smiling. She said: Messenger of Allah. what made thee laugh? He said: A people from my followers were presented to me. They were sailing on the surface of this green sea... (here follows the tradition that has gone before).
وَحَدَّثَنَاهُ مُحَمَّدُ بْنُ رُمْحِ بْنِ الْمُهَاجِرِ، وَيَحْيَى بْنُ يَحْيَى، قَالاَ أَخْبَرَنَا اللَّيْثُ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنِ ابْنِ حَبَّانَ، عَنْ أَنَسِ بْنِ مَالِكٍ، عَنْ خَالَتِهِ أُمِّ حَرَامٍ بِنْتِ مِلْحَانَ، أَنَّهَا قَالَتْ نَامَ رَسُولُ اللَّهِ صلى الله عليه وسلم يَوْمًا قَرِيبًا مِنِّي ثُمَّ اسْتَيْقَظَ يَتَبَسَّمُ - قَالَتْ - فَقُلْتُ يَا رَسُولَ اللَّهِ مَا أَضْحَكَكَ قَالَ ‏ "‏ نَاسٌ مِنْ أُمَّتِي عُرِضُوا عَلَىَّ يَرْكَبُونَ ظَهْرَ هَذَا الْبَحْرِ الأَخْضَرِ ‏"‏ ‏.‏ ثُمَّ ذَكَرَ نَحْوَ حَدِيثِ حَمَّادِ بْنِ زَيْدٍ ‏.‏
