From Sahih Muslim (Hadith 3529):
A'isha (Allah be pleased with her) reported that Allah's Messenger (ﷺ) was asked about a woman whom a man married and then divorced her, and then she married (another) person, and she was divorced before sexual intercourse with her, whether it was lawful for her first husband (to marry her in this state). He (the Holy Prophet) said:No, until he has tasted her sweetness
