A man came to Ibn Abbas and said, "Your freedman, when he prostrates, puts his forehead, his forearms, and his chest on the ground."So Ibn Abbas asked the man, "What makes you do what you do?"He replied, "Humility."Ibn Abbas said, "That is how a dog crouches. I saw the Prophet ﷺ, and when he prostrated, the whiteness of his armpits could be seen."
