[Machine] From Hassan bin Ali: "Leave what causes doubt for what does not cause doubt." Narrated by Al-Nasai and Al-Tirmidhi, and Hasan said it is authentic.
عَنِ الحَسَنِ بْنِ عَلِيٍّ: «دَعْ ما يَرِيبُكَ إلى ما لا يَرِيبُكَ۔» رَواهُ النَّسائِيُّ والتِّرْمِذِيُّ وقالَ حَسَنٌ صَحِيحٌ
I said to al-Ḥasan b. ʿAlī: What did you memorize from the Messenger of Allah ﷺ? He said: I memorized from him: "Leave what makes you doubt for what does not make you doubt."
قُلْتُ لِلْحَسَنِ بْنِ عَلِيٍّ مَا حَفِظْتَ مِنْ رَسُولِ اللهِ ﷺ؟ قَالَ: حَفِظْتُ مِنْهُ «دَعْ مَا يَرِيبُكَ إِلَى مَا لَا يَرِيبُكَ۔»
I said to al-Ḥasan b. ʿAlī: What did you memorize from the Messenger of Allah ﷺ? He said: I memorized from him: "Leave what makes you doubt for what does not make you doubt. The truth brings tranquility while falsehood sows doubt."
قُلْتُ لِلْحَسَنِ بْنِ عَلِيٍّ: مَا حَفِظْتَ مِنْ رَسُولِ اللَّهِ ﷺ؟ قَالَ: حَفِظْتُ مِنْ رَسُولِ اللَّهِ ﷺ: «دَعْ مَا يَرِيبُكَ إِلَى مَا لاَ يَرِيبُكَ، فَإِنَّ الصِّدْقَ طُمَأْنِينَةٌ وَإِنَّ الْكَذِبَ رِيبَةٌ».
