Sunan Abi Dawud 4473

Narrated Ali ibn AbuTalib: A slave-girl belonging to the house of the Messenger of Allah (ﷺ) committed fornication. He (the Prophet) said: Rush up, Ali, and inflict the prescribed punishment on her. I then hurried up, and saw that blood was flowing from her, and did not stop. So I came to him and he said: Have you finished inflicting (punishment on her)? I said: I went to her while her blood was flowing. He said: Leave her alone till her bleeding stops; then inflict the prescribed punishment on her. And inflict the prescribed punishment on those whom your right hands possess (i.e. slaves). Abu Dawud said: A similar tradition has been transmitted by Abu al-Ahwas from 'Abd al-A'la, and also by Shu'bah from 'Abd al-A'la. This version has: He said: Do not give her beating until she gives birth to a child. But the former (version) is sounder.
