Musannaf Ibn Abi Shaybah 19800 — A man who divorces his wife while she

Hammad (may Allah have mercy on him) said: If a man divorces his wife while she has irregular bleeding (istihadah), and she menstruates for the third time for the shortest duration she used to menstruate, her husband no longer has the right to take her back; but she does not take the ritual bath (ghusl) nor pray until the longest duration she used to menstruate has passed over her.
