Whenever he looked at the mirror, Prophet Muhammad (peace and blessings be upon him) is narrated to have made this dua (for example):
O Allah, just as You have made my external features beautiful, make my character beautiful as well.
Is this dua present in sahih hadith books?
(And does it include (may not be accurate): “And please Allah, do not make it a source of Fire.” [Either because I am pleased with it too much, or not pleased with it.])
