Qatadah narrates from Ikrimah, Ata, Tawus and Jabir bin Zayd that all of them narrated from Sayyiduna Abdullah bin Abbas (may Allah be pleased with him) that he said: "It is one separating (ba'in) divorce," meaning concerning a man who gives his wife three divorces before consummating the marriage. It is possible that what is meant by it is separating them, so it does not contradict the earlier hadith.
