“I think that women were created for nothing but evil.” (Hanbal, Musnad, volume 6, p. 86)
Is the above report authentically attributed to the Prophet SAW?
The hadith is as follows:
قالت عائشة: دخل علي رسول الله صلى الله عليه وسلم بسرف وقد نفست وأنا منكسة، فقال لي: " أنفست؟ " فقلت: نعم، يا رسول الله، ولا أحسب النساء خلقن إلا للشر، فقال: " لا، ولكنه شيء ابتلي به نساء بني آدم
Aisha said: The Messenger of Allah ﷺ entered upon me when we were at Sarif and I was menstruating and I was depressed.
The Messenger of Allah ﷺ asked: "Are you in menses?"
I replied: "Yes, and I think that women are only created for evil."
The Messenger of Allah ﷺ said: "No, rather this is a thing with which Allah has tested the daughters of Adam."
Things to consider:
The part you have quoted was not said by the Prophet ﷺ, but rather by Aisha, and the prophet ﷺ negated it.
This hadith with this specific wording is weak because its chain is severed as Abu Ubaid did not meet Aisha.
