Muwatta 1721

Malik transmits from Hisham ibn Urwa, from his father, that a man would divorce his wife and then take her back before her waiting period ended, and that was his right, even if he divorced her a thousand times. A man then set about divorcing his wife until she was close to the end of her waiting period, then took her back, divorced her again, and said: by God, I will never shelter you with me, and you will never be lawful to me. God then revealed the verse in the Surat al-Baqara that divorce is twice, and from that day people started divorce afresh, whether they had divorced or not. ¹
