Foolishly tamper with Ray's Persian rug, perhaps (6,3)
I believe the answer is:
prayer-mat
'persian rug perhaps' is the definition.
I can't judge whether this definition defines the answer.
'foolishly tamper with ray's' is the wordplay.
'foolishly' indicates anagramming the letters.
'with' indicates putting letters inside.
'tamper' is an anagram of 'permat'.
'permat' placed around 'ray' is 'PRAYER-MAT'.
Can you help me to learn more?
(Other definitions for prayer-mat that I've seen before include "Rug used by Muslims during their devotions" , "Small carpet for kneeling at worship" , "Small carpet used by Muslims" .)
