From Sahih Muslim (Hadith 3760):
Abdullah b Shaddad reported that mention was made about the invokers of curses before Ibn 'Abbas (Allah be pleased with them). Ibn Shaddad said:Are these the two about whom Allah's Apostle (ﷺ) said." If I were to stone one without evidence, I would have definitely stoned her"? Ibn Abbas (Allah be pleased with them) said: She is not this woman; but she is the one who (committed adultery) openly
