It was narrated on the authority of Abu Khaldeh that he said: I came with Muhammad bin Sirin, and if a man came, he told him that I saw that I was drinking from a tube and it was with two heads. I drink from one sweet water and from the other bitter salty water. Ibn Sirin said to him: You have a woman and she has a sister, so you use it so repent and return to God Almighty .
