Musnad Ahmad 5:573

Abdullah narrated to us, Ishaq bin Isma'il narrated to us, Waki' narrated to us, from Sufyan—and Abu Khaythama narrated to me, Yazid bin Harun narrated to us, Sufyan narrated to us, from 'Abd al-A'la al-Tha'labi, from Abu Jamila, from 'Ali: That a servant of the Prophet, may God bless him and grant him peace, committed fornication. He ordered me to carry out the prescribed punishment (hadd) upon her. I found that she had not yet dried from her blood (i.e., she had just given birth). I came to him and mentioned that to him. He said: "When she has dried from her blood, carry out the prescribed punishment upon her. Carry out the prescribed punishments upon those whom your right hands possess." This is the wording of the hadith of Ishaq bin Isma'il.
