Musannaf Ibn Abi Shaybah 33701 — Those who used to say: what she bore

Qays bin Sa'd reports from Mujahid, and Ikrimah bin Khalid from Yazid bin Abd al-Malik, that they said: Whatever child the woman bears while her husband is a slave, its wala' belongs to the mother's mawali; and whatever she bears while the father is free, its wala' belongs to the father's mawali.
