Encouragement to Avoid Doubtful Matters
It was narrated that Abu Al-Hawra’ As-Sa’di said: “I said to Al-Hasan bin ‘Ali, may Allah be pleased with him: ‘What did you memorize from the Messenger of Allah [SAW]?’ He said: I memorized from him: ‘Leave that which makes you doubt for that which does not make you doubt.'”
