Sunan al-Nasa'i — The Book of Divorce

“Zam’ah had a slave woman with whom he used to have intercourse, but he suspected that someone else was also having intercourse with her. She gave birth to a child who resembled the one whom he suspected. Zam’ah died when she was pregnant, and Sawdah mentioned that to the Messenger of Allah. The Messenger of Allah said: ‘The child is the bed’s, but veil yourself from him, O Sawdah, for he is not a brother of yours.'”

The Messenger of Allah said: “If a woman goes out to (pray) ‘Isha’, let her not touch perfume.”
