عَنْ أَبِي مُحَمَّدٍ الْحَسَنِ بْنِ عَلِيِّ بْنِ أَبِي طَالِبٍ سِبْطِ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ وَرَيْحَانَتِهِ رَضِيَ اللَّهُ عَنْهُمَا، قَالَ: حَفِظْتُ مِنْ رَسُولِ اللَّهِ صَلَّى اللَّهُ عَلَيْهِ وَسَلَّمَ: دَعْ مَا يَرِيبُكَ إِلَى مَا لَا يَرِيبُكَ. رَوَاهُ التِّرْمِذِيُّ وَالنَّسَائِيُّ، وَقَالَ التِّرْمِذِيُّ: حَدِيثٌ حَسَنٌ صَحِيحٌ

11 – It is reported on the authority of Abī Muḥammad al-Ḥasan bin ‘Alī bin Abī Ṭālib, the grandson of the Messenger of Allāh (peace and blessings of Allāh be upon him), and his beloved (may Allāh be pleased with them both) who said:

I memorized from the Messenger of Allāh (peace and blessings of Allāh be upon him): “Leave that which makes you doubt for that which does not make you doubt.” [Reported by Tirmidhī and Nasā’ī] And Tirmidhī said: It is a ḥasan ṣaḥīḥ ḥadīth.
