«نُومِ الظَّالِمْ عِبَادَهْ»

The saying claims, with bitter irony, that when a wrongdoer sleeps, his rest counts as worship. The religious term is used sarcastically, not as a literal claim about his piety: while unconscious, he cannot mistreat anyone, so his inactivity accomplishes more good than anything he does while awake.

The saying does not praise sleep in general; it concerns only someone whose waking activity causes harm. The hours asleep also keep him from piling up further guilt. Sleep shields others from his harm and spares him additional sin, which is why it can be likened to an act of devotion.

A wry remark about someone known for harming others, implying that the best thing they can do is stay idle or out of the way. Because it labels the person an oppressor, it is a pointed accusation rather than a neutral observation and may give offense.
