(4) باب الْوُضُوءِ بِمَاءِ الْبَحْرِ
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 seawater?' The Messenger of Allah (ﷺ) said: 'Its water is a means of purification and its dead meat is permissible.'" (FR)
