Beware of suspicion
إِيَّاكُمْ وَالظَّنَّ، فَإِنَّ الظَّنَّ أَكْذَبُ الْحَدِيثِ، وَلَا تَحَسَّسُوا، وَلَا تَجَسَّسُوا
Iyyakum wa-dh-dhann, fa-inna-dh-dhanna akdhabu-l-hadith, wa la tahassasu, wa la tajassasu.
"Beware of suspicion, for suspicion is the most untruthful of speech. Do not look for one another's faults, and do not spy on one another."
Narrated by Abu Hurayrah. Sahih al-Bukhari 6066, Sahih Muslim 2563
A short reflection
Most suspicion is a story we tell ourselves and then believe. Give the benefit of the doubt you would want for yourself.
