Yahya related to me from Malik that Ibrahim ibn Uqba asked Saidibn al-Musayyab about suckling. Said said, "All that occurs in thefirst two years, even if it is only a drop, makes haram. Whatever isafter two years, is only food that is eaten."Ibrahim ibnUqba said, ''Then I asked Urwa ibn az-Zubayr and he told me the sameas what Said ibn al-Musayyab said."
