Muwatta Malik, Book 29, Hadith 1231 (In-Book)

Yahya related to me from Malik from Yahya ibn Said that Said ibn al-Musayyab said, "Divorce belongs to men, and women have the idda."

وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ يَحْيَى بْنِ سَعِيدٍ، عَنْ سَعِيدِ بْنِ الْمُسَيَّبِ، أَنَّهُ كَانَ يَقُولُ الطَّلاَقُ لِلرِّجَالِ وَالْعِدَّةُ لِلنِّسَاءِ ‏.‏
