إِنَّ نَفْسًا لَنْ تَمُوتَ حَتَّى تَسْتَكْمِلَ رِزْقَهَا
Translation: No soul will die until it has received its full allotted provision.
Source: رواه في شرح السنة
نَفْسًا refers to any soul, and لَنْ تَمُوتَ denies its death before the specified condition. Trust in Allah should encourage lawful conduct and guard against panic. Belief in allotted provision does not instruct people to stop working, seeking treatment, or fulfilling their responsibilities.
لَنْ is a particle of negation that places the present verb تَمُوتَ in the accusative/subjunctive form. حَتَّى means “until” and governs the subjunctive تَسْتَكْمِلَ. The suffix هَا in رِزْقَهَا refers back to نَفْسًا.
Trust and lawful effort are complementary: conviction guides the heart while appropriate action continues.
