Ruling on greeting and socializing with one whose number of breastfeedings is unknown

Question:
This questioner, the mother of Bandar from the Holy City of Madinah, says in this question: A woman breastfed her child for a full day, but she does not know how many feedings it was. He is now a man. Is it permissible for him to greet her, her daughters, and her husband's daughters from another wife? Please inform us, O Shaykh.

Answer:
He is not to greet her, nor her daughters, until she knows that she breastfed him five times or more on that day. A feeding is defined as him holding the breast and sucking the milk until it flows into his stomach, then releasing it, either to move to another breast or for other reasons. As for if she... breastfed him on the second day, Monday or Wednesday, but I do not know if she breastfed him five times, three times, or two times, I do not know?
This is sufficient, and he does not become her son until she is certain and knows with certainty that she breastfed him five times or more. This is based on what is established from the Prophet (peace and blessings be upon him) that he said to Sahlah bint Sahil: And what is established from A'ishah (may Allah be pleased with her) that she said: "Among what was revealed in the Qur'an were ten known breastfeedings that make marriage forbidden, then they were abrogated by five known breastfeedings. The Prophet (peace and blessings be upon him) passed away while the matter was still as such." The Prophet (peace and blessings be upon him) passed away while the matter was still as such. Muslim narrated it in his Sahih, and al-Tirmidhi in his Jami', and this is his wording. Yes.
