"So they went in search of water and met a woman who was sitting on her camel between two bags of water. They asked, "Where can we find water?" She replied, "I was there (at the place of water) this hour yesterday and my people are behind me." They requested her to accompany them. She asked, "Where?" They said, "To Allah's Messenger (ﷺ) ." She said, "Do you mean the man who is called the Sabi, (with a new religion)?" They replied, "Yes, the same person. So come along."...She returned home late. Her relatives asked her: "O so and so what has delayed you?" She said, "A strange thing! Two men met me and took me to the man who is called the Sabi' and he did such and such a thing."
