tirmidhi:2993Muḥammad b. Bashhār > Abū Dāwud al-Ṭayālisī > Abū ʿĀmir / al-Khazzāz Wayazīd b. Ibrāhīm > Ibn Abū Mulaykah > Yazīd > Ibn Abū Mulaykah > al-Qāsim b. Muḥammad > ʿĀʾishah Walam > Abū ʿĀmir al-Qāsim

"I asked the Messenger of Allah ﷺ about Allah's saying: So, as for those in whose hearts there is a deviation, they follow that which is not entirely clear thereof, seeking Al-Fitnah and seeking its Ta'wil (3:7). He said: 'When you see them, be aware of them.'" Yazid (one of the narrators in the chain) said: "When you see them, be aware of them' - she said it two or three times."  

Abū ʿĪsá said that this Ḥadīth is Ḥasan-Ṣaḥīḥ.
الترمذي:٢٩٩٣حَدَّثَنَا مُحَمَّدُ بْنُ بَشَّارٍ حَدَّثَنَا أَبُو دَاوُدَ الطَّيَالِسِيُّ حَدَّثَنَا أَبُو عَامِرٍ وَهُوَ الْخَزَّازُ وَيَزِيدُ بْنُ إِبْرَاهِيمَ كِلاَهُمَا عَنِ ابْنِ أَبِي مُلَيْكَةَ قَالَ يَزِيدُ عَنِ ابْنِ أَبِي مُلَيْكَةَ عَنِ الْقَاسِمِ بْنِ مُحَمَّدٍ

عَنْ عَائِشَةَ وَلَمْ يَذْكُرْ أَبُو عَامِرٍ الْقَاسِمَ قَالَتْ سَأَلْتُ رَسُولَ اللَّهِ ﷺ عَنْ قَوْلِهِ ( فَأَمَّا الَّذِينَ فِي قُلُوبِهِمْ زَيْعٌ فَيَتَّبِعُونَ مَا تَشَابَهَ مِنْهُ ابْتِغَاءَ الْفِتْنَةِ وَابْتِغَاءَ تَأْوِيلِهِ ) قَالَ فَإِذَا رَأَيْتِيهِمْ فَاعْرِفِيهِمْ وَقَالَ يَزِيدُ فَإِذَا رَأَيْتُمُوهُمْ فَاعْرِفُوهُمْ قَالَهَا مَرَّتَيْنِ أَوْ ثَلاَثًا  

قَالَ أَبُو عِيسَى هَذَا حَدِيثٌ حَسَنٌ صَحِيحٌ
