For what they do not know, meaning their deities. The meaning of 'they do not know them' is that they call them gods and believe that they harm and benefit and intercede with Allah, but that is not the case. Their reality is that they are inanimate objects that do not harm or benefit, so they are ignorant of them. It is said that the pronoun in 'they do not know' refers to the deities. That is, to things not described by knowledge, nor do they feel. Do they make for them a share in their livestock and crops or not? They would allocate that to them as a means of drawing closer to them. You will surely be questioned about what you used to fabricate regarding the falsehood in your claim that they are gods and that they are deserving of being approached.
