Most scholars of knowledge consider gathering between a woman and her stepdaughter permissible, with no harm in it. This was practiced by Abdullah ibn Ja'far and [Abdullah ibn] Safwan ibn Umayyah. All other jurists have also expressed this view, with the exception of al-Hasan, 'Ikrimah, and Ibn Abi Layla.

Whenever the woman bears a child from that man, he becomes a paternal uncle and a maternal uncle to the children of them both.
