Q: i am told to redo my sacrifice because we skinned the animal 10 minutes after slaughter.  Also, the head was not fully cut off only the vines were.  please inform me if i should redo (email)

A: Your sacrifice is complete.  The head does not get fully cut off.  The major veins only needs to be cut off.  (Some of the information you received appears to be incorrect.)

Allah Certainly Knows Best.
