وعن ابن مسعود رضي الله عنه أنه أتي برجل فقيل له، هذا فلان تقطر لحيته خمرًا، فقال: إنَّا قد نهينا عن التجسس، ولكن إن يظهر لنا شئ، نأخذ به". حديث حسن صحيح رواه أبو داود بإسناد على شرط البخاري ومسلم.
It has been reported that a man was brought before Abdullah bin Mas'ud (May Allah be pleased with him) because his beard was giving out smell of wine. Ibn Mas'ud said:
"We have been prohibited from spying (on Muslims) and finding faults (with them). But we can take to task only and only if the sin is overt.
[Abu Dawud].
Reported by Abu Dawud (No. 4890). Cited in Riyad as-Salihin (No. 1572).
Ibn Mas‘ūd (may Allah be pleased with him) reported: A man was brought to him and it was said: "This is so-and-so, and his beard is dripping with wine." Thereupon he said: "We have been prohibited from spying. However, if we see something evident, we will act upon it."
