In a Hanafi legal example, audible laughter within prayer carries specified consequences for ablution. An objector asks why a severe false accusation during prayer should not also invalidate ablution, since false accusation is morally more serious.
The objection treats the seriousness of a sin as if it were the legally effective cause of ablution being invalidated. The analysis separates moral gravity from the specific evidence and conditions governing ritual purity.
Result: The fact that one act is more sinful than another does not establish that both carry the same ritual consequences.
