Chapter 85: Laws of Inheritance (Al-Faraa'id)
Narrated Ibn 'Umar: A man and his wife had a case of Lian (or Mula' ana) during the lifetime of the Prophet (ﷺ) and the man
denied the paternity of her child. The Prophet (ﷺ) gave his verdict for their separation (divorce) and then
the child was regarded as belonging to the wife only.
