Sahih Muslim Book 17, Hadith Number 4225.

Chapter : The prescribed punishment should be deferred in case of one who is in a state of parturition.

This hadith has been narrated on the authority of as-Suddi with the same chain of transmitters, but he did not mention: “Those who are married and those who are not married.” There is also an addition in it: “I spare her until she is all right.”
