Musannaf Ibn Abi Shayba 34:283

Yahya ibn Yaman narrated to us, from Ash'ath, from Ja'far, from Sa'id ibn Jubayr, regarding [the verse]: "Man was created of haste." He said: Adam, peace and blessings be upon him, was created, then the soul was blown into him. The first thing that was blown into was his knees, so he went to rise, and He said: "Man was created of haste."
