وَحَدَّثَنِي عَنْ مَالِكٍ، عَنْ إِبْرَاهِيمَ بْنِ عُقْبَةَ، أَنَّهُ سَأَلَ سَعِيدَ بْنَ الْمُسَيَّبِ عَنِ الرَّضَاعَةِ، فَقَالَ سَعِيدٌ كُلُّ مَا كَانَ فِي الْحَوْلَيْنِ وَإِنْ كَانَتْ قَطْرَةً وَاحِدَةً فَهُوَ يُحَرِّمُ وَمَا كَانَ بَعْدَ الْحَوْلَيْنِ فَإِنَّمَا هُوَ طَعَامٌ يَأْكُلُهُ ‏.‏ قَالَ إِبْرَاهِيمُ بْنُ عُقْبَةَ ثُمَّ سَأَلْتُ عُرْوَةَ بْنَ الزُّبَيْرِ فَقَالَ مِثْلَ مَا قَالَ سَعِيدُ بْنُ الْمُسَيَّبِ ‏.‏

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." Translation Not Available
