2. Muhammad ibn Yahya has narrated from Ahmad ibn Muhammad from ibn Mahbub from Hisham ibn Salim from Muhammad ibn Muslim who has said the following: “I once heard abu Ja’far عليه السلام, saying, ‘A slave-girl is not required to wear a veil for Salat (prayer) as well as one who has planned for her freedom; and the one who has already contracted even if wearing veil for Salat (prayer) is made a condition when she is owned until she pays off all that is contracted and all things applicable to slaves in penal law apply to her also.’”
