The Doubtful Number of Breastfeedings and Satisfying the Wet Nurse

Question:
And Honorable Shaykh, may Allah grant you success, my grandmother (may Allah have mercy on her) used to say that so-and-so had breastfed her. When I asked her how many times the breastfeeding occurred, she said, "I do not know, except that I was satisfied." My grandmother was of sound mind until she passed away. The question is: Do I consider this woman my aunt through breastfeeding, especially since she said that in the old days they did not count the feedings, but rather considered satisfaction?

Answer:
If she was satisfied, it is known that more than five sucks constitute the breastfeeding intended by the term "suck." The intended meaning of "suck" is a full feed, meaning that the child sucks the breast and milk appears from it, then he leaves it, then returns to it, and so on until he completes five. These are the feedings, meaning the sucks. If he was satisfied, it means he took more than five sucks. But if there is doubt, there is no doubt that this establishes a suspicion. The Muslim avoids suspicions. Leave what makes you doubt for what does not make you doubt. Whoever avoids suspicions has purified his religion.
