What are the conditions for the forfeiture of 'adalah (uprightness/integrity), and is a religious scholar or cleric going out into the street or marketplace bareheaded (i.e., not wearing a turban) considered a reason for the forfeiture of his 'adalah?

Justice is forfeited by committing acts of disobedience (fisq), engaging in major sins, persistently committing minor sins, or by performing actions that diminish one's integrity (murū’ah), even if permissible. This varies depending on environments and customs. Thus, a just person is one who largely avoids major sins, is cautious about minor sins, and refrains from actions that compromise integrity. A scholar or sheikh walking bareheaded is permissible according to Islamic law (shar‘an), but it may be considered a flaw in certain environments or customs. The criterion for justice is being free from anything that would cause the doer to be condemned, either in the religious law or in the view of their society, and this varies across societies.
