What are the forbidden breastfeedings?

Question:
The questioner (M. S. F) says: What are the forbidden breastfeedings? We ask for your guidance on this?

Answer:
The forbidden breastfeedings must be five or more, each breastfeeding being distinct. The child sucks the breast until the milk reaches his stomach, then he is separated from the breast, and then he returns in that same session or in another session until he completes five on one breast or on both breasts. This is the legislated breastfeeding that is forbidden: five or more. This is based on the statement of the Prophet (peace and blessings be upon him) to Sahlah bint Sahil: And it is established in the authentic collections that Aisha (may Allah be pleased with her) said: "Among what was revealed in the Qur'an were ten known breastfeedings that prohibit marriage, then they were abrogated by five known breastfeedings. The Prophet (peace and blessings be upon him) passed away while the matter remained as such." This was narrated by Imam Muslim in his Sahih, and by Imam al-Tirmidhi in his Jami', and this is his wording. From this, it is known that it is necessary for there to be five breastfeedings or more within the two-year period. This is based on the statement of the Prophet (peace and blessings be upon him): And each breastfeeding is distinct on its own: the child sucks the breast, swallows the milk, and the breast is removed from his mouth. If a woman knows this and testifies to it, or more than one trustworthy woman testifies to it, then this is acted upon: five breastfeedings or more. However, if the woman does not know whether it was five or less or more, or does not know whether the milk reached his stomach or not, then this is not acted upon, and the rulings of breastfeeding are not established by it, until it is established that he breastfed five times, each one distinct, and that the milk reached his stomach, and that this occurred within the two-year period, and that a trustworthy woman or more testifies to this. Yes.
