3. A number of our people have narrated from Sahl ibn Ziyad from Ahmad ibn Muhammad from ibn abu Nasr from Hammad ibn ‘Uthaman who has said the following
“I once heard abu ‘Abd Allah (a.s.), saying, ‘Breastfeeding after weaning is not effective.’ I then said, ‘I pray to Allah to keep my soul in service for your cause, what is al-Fatam (weaning)?’ He (the Imam) said, ‘It is the two years that Allah, most Majestic, most Glorious, has mentioned (in His book).’ (2:233)”
