وَلَا تُحَمِّلْ نَفْسَكَ مَا لَا تُطِيقُ.
Do not impose on yourself what you cannot bear.
This prohibition supplies a reasonable limit to the preceding instructions. It prevents the advice about work and commitments from being heard as unlimited demands. In a context where that mistaken inference is likely, the clause can serve an iḥtirās-like protective function.
However, not every additional limiting sentence automatically qualifies as technical iḥtirās. If no misleading inference is plausibly invited by the prior commands, the same clause can simply be another independent instruction. The presence of a real risk of misunderstanding is decisive.
