Narrated Anas ibn Malik: The Prophet (ﷺ) had himself cupped three times in the veins at the sides of the neck and on the shoulder. Ma'mar said: I got myself cupped, and I lost my memory so much so that I was instructed Surat al-Fatihah by others in my prayer. He had himself cupped at the top of his head.
