Hadith.3732 - Hafs ibn Al-Bakhtari narrated from Al-Husayn ibn Al-Mundhir who said
I said to Abu Abdillah (as), "My wife gave me money to use as I wish. Can I buy a bondwoman with her money and have relations with her?"
Imam (as) said: "No. She gave it to you to bring comfort to her eyes, and you intend to cause her distress."
