Yes. At the end of his life:
Anas bin Malik said, “Any of the female slaves of Medina could take hold of the hand of Allah’s Messenger and take him wherever she wished.”
Sahih al-Bukhari 6072
Bee/Wasp
16:68 And your Lord inspired to the bee, “Take for yourself among the mountains, houses, and among the trees and [in] that which they construct. 69 Then eat from all the fruits and follow the ways of your Lord laid down [for you].”
There emerges from their bellies a drink, varying in colors, in which there is healing for people.
Indeed in that is a sign for a people who give thought.
Koran 16:68-69
Muhammad shows his lack of observation with: “eat from all the fruits”. Bees do not eat fruit. They sip nectar from flowers. It’s wasps that eat fruit. Bees will eat fruit and sweet substances when they can’t find nectar.
Obviously, bees drinking nectar is incoherent with bees being told to “eat from all the fruits”. Bees do NOT “follow the ways of your Lord laid down [for you].”
Obviously, wasps eating fruit is incoherent with bees being told to “eat from all the fruits”. Obviously, bees (and wasps) do NOT “follow the ways of your Lord laid down [for you].”
This shows that Muhammad couldn’t tell bees and wasps apart and thought they were the same.
