He says: How did Allah create Hawwa? Allah knows best, but it is well-known that she was created from a rib.
As the Prophet ﷺ said: Woman was created from a rib.
And the most crooked part of the rib is its upper part, so originally she was created from a rib, and it is well-known that she was created from the rib of Adam, because Allah the Blessed and Exalted: and He created from it.
His wife, meaning from this soul which is the soul of Adam, He created from it his wife, who is.
