The tradition mentioned above has also been transmitted by Sahl bin Sa’d Al Sa’idi through a different chain of narrators. This version adds the child was attributed to its mother.
Sunan Abi Dawud Book 13, Hadith 75
← Previous Hadith Sahl bin Sa’ad reported the Apostle of Allaah(ﷺ) as saying - in the tradition of spouses who invoked curses to each other “Look if she bears a child which has very black eyes, large buttocks, I cannot but imagine that he (i.e., ‘Uwaimir) has spoken the truth. But, if she bears a reddish child like the lizard with red spots (waharah), I cannot imagine that ‘Uwaimir has lied against her. She gave birth to a child (like that described the Prophet (ﷺ) ) in a detestable manner.

Sunan Abi Dawud Book 13, Hadith 74 Next Hadith → The tradition mentioned above has also been transmitted by Sahl bin Sa’d Al Sa’idi through a different chain of narrators. This version has “He divorced her three times before the Messenger of Allah (ﷺ). The Messenger of Allah (ﷺ) implemented it and what is done before the Prophet (ﷺ) is sunnah(model behavior of the Prophet).

Sahl said “I attended this before the Messenger of Allah(ﷺ). Afterwards the sunnah about those who invoked curses on each other was established that they (the spouses) were separated from each other and they would never be united.”
