This is not the Shiite youtube I had in mind but this one parallels it.
Mohammed might have had predilections for young women but Suni texts cannot be relied on because the Shiites follow history more closely whereas Sunis are inventive
(the following series of videos I believe touch on it but also relate to many Suni falacies regarding jewish woman poisoning mohammed. Aisha , his wife, did it https://youtu.be/27EzUY5evqU )
Thanks.
