Narrated by Hisham's father
From Al-Mughira bin Shu'ba, 'Umar consulted the companions about the case of a woman's abortion (caused by somebody else). Al-Mughlra said: The Prophet gave the verdict that a male or female slave should be given (as a Diya). Then Muhammad bin Maslama testified that he had witnessed the Prophet giving such a verdict.
