Will i be punish

Assalamu alaikum
A room was entered with a shoe that was woer to toilet and the water touched the room floor and dry & kids bed was spread on the floor sometimes they urine touch the floor so we clean the floor everyday but today we didn’t and a guest came and ablute and entered the room with bare foot to pray. I wanted to tell that the floor was not clean but I didn’t saying she didn’t know and she’ll be not be hold at fault. So I prayed on the same praying mat and I was praying I starting thinking what if the guest has matched on a place that there’s impurity in the room and has touched the praying mat but I ignore it because am suffering from waswasa/strong doubt and I read a fatwa that if am not certain I should ignore so i ignored it and continue my prayer. My question is would I be hold at fault for not telling the guest that there might be impurity on the floor as I can’t say where exactly the impurity is? My heart is not at ease.
