[10/-] al-Kafi: Ali b. Ibrahim from his father from Ibn Abi Umayr from Mansur b. Yunus from Mansur b. Hazim from Abi Abdillah عليه السلام who said: the messenger of Allah صلى الله عليه وآله said: there is no suckling after weaning, there is no joining [two consecutive days] in fasting, there is no orphanhood after nocturnal emission, there is no vow of silence from morning to night, there is no return to the nomadic ways after migration [to the urban center of faith], there is no Hijra after the conquest [of Makka], there is no divorce before marriage, there is no setting free [of a slave] before ownership, there can be no oath from a child without the consent of his father, nor from a slave without the consent of his master, nor for a woman without the consent of her husband, there can be no promise to do an evil, nor an oath to break blood-ties.

The meaning of his words: there is no suckling after weaning is that – a child if he drinks the milk of a woman after he has been weaned off milk [two years] then that suckling does not prevent marriage [she does not become his Mahram/foster mother].
[-/10] الكافي: علي بن إبراهيم، عن أبيه، عن ابن أبي عمير، عن منصور بن يونس، عن منصور بن حازم، عن أبي عبدالله عليه السلام قال: قال رسول الله صلى الله عليه وآله: لارضاع بعد فطام ولا وصال في صيام ولا يتم بعد احتلام ولا صمت يوما إلى الليل ولا تعرب بعد الهجرة ولا هجرة بعد الفتح ولا طلاق قبل نكاح ، ولا عتق قبل ملك ، ولا يمين للولد مع والده ولا للمملوك مع مولاه ولا للمرأة مع زوجها ولا نذر في معصية ولا يمين في قطيعة فمعنى
قوله: لا رضاع بعد فطام ان الولد إذا شرب لبن المرأة بعد ما تفطمه لا يحرم ذلك الرضاع التناكح
