Chapter 7 | On One who Takes A Female Slave and Doesn’t Have Sexual Intercourse with Her Once Every Forty Days as a Result of which She Commits A Forbidden Act
22-8 حدثنا محمد بن الحسن بن أحمد بن الوليد رضي الله عنه قال: حدثنا محمد بن الحسن الصفار، عن يعقوب بن يزيد، عثمان بن عيسى، عمن ذكره، عن أبي عبد الله عليه السلام قال: من اتخذ جارية فلم يأتها في كل أربعين يوما كان وزر ذلك عليه
22-8 Muhammad ibn al-Hassan ibn Ahmad ibn al-Walid - may God be pleased with him - narrated that Muhammad ibn al-Hassan al-Saffar quoted Yaqoob ibn Yazid, on the authority of Uthman ibn Isa who linked it up through a chain of narrations to Aba Abdullah as-Sadiq (MGB), “If one takes a female slave and doesn’t have sex with her once every forty days, he would be held responsible for her sins.”
