إِنَّ الرَّجُلَ لَيُحْرَمُ الرِّزْقَ بِالذَّنْبِ يُصِيبُهُ
Translation: A person may be deprived of provision because of a sin he commits.
Source: ابن ماجه
Sin may have harmful consequences in life; dishonest earnings, broken trust, and injustice undermine what is beneficial in provision. The statement encourages repentance and moral self-examination. It does **not** authorize assuming that every poor or struggling person is being punished for a known sin.
الرَّجُلَ is the noun of إِنَّ. لَيُحْرَمُ is a passive present-tense verb, “is deprived,” with an emphatic lām. بِالذَّنْبِ expresses cause; يُصِيبُهُ means “which he commits” in context.
One should combine repentance, honesty, fulfilled obligations, and practical effort when seeking provision.
