al-Akhdr bin Ajlan al-Shybany الأخضر بن عجلان الشيباني البصري · The Chapters on Legal Punishments

“Whoever conceals the (hidden) fault of his Muslim brother, Allah (SWT) will conceal his faults on the Day of Resurrection. Whoever exposes the fault of his Muslim brother, Allah will expose his faults, until (so that) He shames him, due to it, in his (own) house.”
