Hadith.4334 - Jamil ibn Salih narrated that he had a female slave in Medina whose menstruation had stopped. He made a vow to Allah (swt), the Almighty and Glorious, that if she began to menstruate, he would fulfill a certain obligation. Later, he learned that she had already menstruated before he made the vow. He wrote to Abu Abdillah while he was in Medina, asking for guidance. Abu Abdillah replied: "If she had menstruated before the vow, then there is no obligation upon you. However, if she menstruated after the vow, then the vow is binding upon you."
