I heard Messenger of Allah (ﷺ) say: But between them are certain doubtful things which many people do not recognize. He who guards against doubtful things keeps his religion and his honor blameless, but he who falls into doubtful things falls into what is unlawful.
Hadith Commentary: Sunan Abi Dawud 3330
This profound narration from the Messenger of Allah (ﷺ) addresses the critical Islamic principle of wara' (piety and caution) in matters of religious practice and daily conduct, particularly relevant to the discussions in Commercial Transactions (Kitab Al-Buyu).
The Nature of Doubtful Matters
The "doubtful things" (al-shubuhat) refer to matters whose legal status is ambiguous - neither clearly lawful (halal) nor clearly unlawful (haram). Many people lack the religious insight to recognize these gray areas, making them particularly dangerous for the unwary believer.
Scholars explain these include transactions with questionable elements, earnings from sources of mixed legitimacy, and actions where evidence of permissibility is weak or contradictory. The wise Muslim exercises caution in such matters.
The Reward of Caution
"He who guards against doubtful things keeps his religion and his honor blameless" - This protection yields two great benefits: preservation of one's religion from spiritual corruption, and protection of one's honor from suspicion and slander. When people see an individual avoiding doubtful matters, they trust his integrity in both religious and worldly affairs.
The Danger of Negligence
"He who falls into doubtful things falls into what is unlawful" - This demonstrates the slippery slope principle in Islamic ethics. Habitual engagement in ambiguous matters desensitizes the conscience and gradually leads to committing clear prohibitions. The heart that becomes accustomed to gray areas loses its sensitivity to recognize outright haram.
Practical Application in Commerce
In Kitab Al-Buyu, this principle requires merchants to avoid transactions with even slight elements of uncertainty - such as unclear pricing, ambiguous quality, or conditions that might contain riba (interest). The pious Muslim businessman seeks clear, transparent dealings to protect both his religion and his commercial reputation.
