Breastfeeding Adults
The traditional narrative suggests it was one time exception for Salim (adult) only w/ some sort of cup over 4 or 5 days. It is also suggested all wives of the Prophet (AS) except Ayesha (RA) considered it to be an exception made for Salim. I haven’t researched this topic much. The videos posted above deal with a similar yet different issue (not adult).
Ghamidi sb’s interpretation and explanation is very convincing but then i came across this article and im utterly confused. https://www.google.ae/amp/s/theislamissue.wordpress.com/2019/02/15/breastfeeding-adults-in-islam/amp/
