Abu Hurairah said: "A man asked the Prophet (ﷺ): 'O Messenger of Allah, we travel by sea and we take a little water with us, but if we use it for Wudu', we will go thirsty. Can we perform Wudu', with sea-water?' The Messenger of Allah (ﷺ) said: 'Its water is a means of purification and its dead meat is permissible.'"

أَخْبَرَنَا قُتَيْبَةُ، عَنْ مَالِكٍ، عَنْ صَفْوَانَ بْنِ سُلَيْمٍ، عَنْ سَعِيدِ بْنِ سَلَمَةَ، أَنَّ الْمُغِيرَةَ بْنَ أَبِي بُرْدَةَ، مِنْ بَنِي عَبْدِ الدَّارِ أَخْبَرَهُ أَنَّهُ، سَمِعَ أَبَا هُرَيْرَةَ، يَقُولُ سَأَلَ رَجُلٌ رَسُولَ اللَّهِ صلى الله عليه وسلم فَقَالَ يَا رَسُولَ اللَّهِ إِنَّا نَرْكَبُ الْبَحْرَ وَنَحْمِلُ مَعَنَا الْقَلِيلَ مِنَ الْمَاءِ فَإِنْ تَوَضَّأْنَا بِهِ عَطِشْنَا أَفَنَتَوَضَّأُ مِنْ مَاءِ الْبَحْرِ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏ "‏ هُوَ الطَّهُورُ مَاؤُهُ الْحِلُّ مَيْتَتُهُ ‏"‏ ‏.‏
