I heard the Messenger of Allah (ﷺ) say: What is lawful is clear and what is unlawful is clear, but between them are certain doubtful things. I give you an example for this. Allah has a preserve, and Allah's preserve is the things He has declared unlawful. He who pastures (his animals) round the preserve will soon fall into it. He who falls into doubtful things will soon be courageous.
Hadith Commentary: The Clear, Unclear, and Doubtful
This profound narration from Sunan Abi Dawud 3329, found in the Book of Commercial Transactions (Kitab Al-Buyu), establishes fundamental principles for distinguishing between lawful (halal) and unlawful (haram) matters in Islamic jurisprudence.
The Three Categories of Actions
The Prophet (ﷺ) delineates three distinct spheres: matters clearly permissible by textual evidence, matters clearly prohibited by definitive proofs, and an intermediate zone of doubtful matters where evidence may be ambiguous or conflicting.
Scholars explain that the clear lawful matters include what Allah has explicitly permitted through Quranic verses or authentic hadiths, while clear unlawful matters encompass what has been definitively forbidden through equally strong evidence.
The Preserve Metaphor Explained
The "preserve" (hima) represents the boundaries set by Allah - His prohibitions. Just as animals grazing near a protected area risk straying into it, those who frequently engage in matters bordering on prohibition risk crossing into actual prohibition.
Classical commentators note that this metaphor emphasizes the importance of maintaining safe distance from doubtful matters to avoid accidental transgression of divine limits.
Spiritual Consequences of Doubtful Matters
The warning that "he who falls into doubtful things will soon be courageous" indicates a gradual spiritual decline. Initially cautious engagement with gray areas eventually leads to boldness in approaching clearly prohibited matters.
Scholars emphasize that this progression demonstrates how the soul becomes desensitized to sin through repeated exposure to borderline actions, ultimately losing its natural aversion to wrongdoing.
Practical Application in Commercial Transactions
In business dealings, this principle requires Muslims to avoid transactions with even slight elements of uncertainty (gharar) or resemblance to prohibited practices like riba (usury).
The pious approach is to exercise caution (wara') by leaving doubtful matters in favor of what is clearly permissible, thus protecting one's religion and worldly affairs from potential harm.
