Hadith.4560 - Dawud ibn al-Husayn narrated from Abu al-Abbas al-Baqbaq, who said
I asked Abu Abdillah (as): "Can a man marry a bondwoman without the knowledge of her owners?"
Imam (as) said: "That is considered fornication. Indeed, Allah (swt), the Mighty and Majestic, says:
'Then marry them with the permission of their owners' (Surah An-Nisa, 4:25)."
