What is the meaning of "he sprinkled on him from his wudu"?

The questioner : His statement: from the Prophet's (peace and blessings be upon him) surplus, or from what remained?

The Shaykh : His statement: means from the water with which he performed wudu. It is possible that the Messenger (peace and blessings be upon him) sprinkled on him when he washed one of his limbs, sprinkling on him like this, meaning he shook it off on him. It is also possible that he scooped water with his hand and then sprinkled it, and this is the most likely.
