Who is this?!
Said after someone crept up quietly from behind and pulled him into a tight embrace while he was busy selling goods in the marketplace.
Who is going to buy this abd (slave) from me?
Said in jest, meaning "abd Allah," a slave of Allah.
O Messenger of Allah ﷺ, in that case, you are going to get a very bad bargain: I am not going to sell very expensively.
You are very expensive in the eyes of Allah.
