Sahih Muslim
The Book of Marriage (Kitab Al-Nikah)
Book Number: 008 / Hadith Number: 3357
'A'isha (Allah be pleased with her) reported that Allah's Messenger (may peace be upon him) 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.
