A woman had a miscarriage before the delivery was due and lost her fetus as a result of a crime committed against her. It was usual for the just leader ‘Umar ibn al-Khattāb (may Allah be pleased with him) to consult his companions and the knowledgeable among them concerning his affairs and issues. So, when this woman miscarried her incomplete, dead fetus, he was unsure about the ruling concerning its blood money. So, he consulted the Companions (may Allah be pleased with them,) on this matter. Al-Mughīrah ibn Shu‘bah informed him that he witnessed the Prophet (may Allah's peace and blessings be upon him) rule that a male or female slave should be given as the fetus' blood money. So, ‘Umar wished to verify this ruling, which was to be a general legislation until the Day of Resurrection. So, he emphatically asked Al-Mughīrah to bring someone who would testify to the truthfulness of his statement and its accurate conveyance. Muhammad ibn Maslamah al-Ansāri testified to the truthfulness of what Al-Mughīrah had said - (may Allah be pleased with all of them).
