Abu Darda' (RA) related from the Prophet ( صلی اللہ علیہ وسلم ) of Allah ( صلی اللہ علیہ وسلم ) that he came upon a woman who was in the advanced stage of pregnancy at the door of a tent. He (the Holy Prophet) said: Perhaps he (the man accompanying her) intends to cohabit with her. They said: Yes. Thereupon Allah's Messenger ( صلی اللہ علیہ وسلم ) said: I was about to curse him with such a curse as may go along with him to his grave. How can he own him (the child to be born) and that is not lawful for him, and how can he take him as a servant for that is not lawful for him?

A hadith like this has been transmitted on the authority of Shu'bah.
