Placing kitab in a bad place

Assalamu alaykum,I placed a kitab with Allah’s name in it and lots of important duas on a radiator to dry. When I put it on to dry I forgot that I had put a pair of boxers on their to dry a couple of days ago but they were clean. Does this mean I have to clean the kitab somehow?

Answer

Wa Alaykum Salaam

One is not required to clean the Kitaab in this case.
