Narrated 'Aishah:"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
