Al-Adab Al-Mufrad
Book 56, Hadith 5
حَدَّثَنَا إِسْمَاعِيلُ قَالَ: حَدَّثَنِي مَالِكٌ، عَنْ أَبِي الزِّنَادِ، عَنِ الأَعْرَجِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللهِ صلى الله عليه وسلم قَالَ: مِنْ شَرِّ النَّاسِ ذُو الْوَجْهَيْنِ، الَّذِي يَأْتِي هَؤُلاَءِ بِوَجْهٍ، وَهَؤُلاَءِ بِوَجْهٍ.

Isma‘il related to us: Malik related to me, from Abu al-Zinad, from al-A‘raj, from Abu Hurayrah, that the Messenger of Allah, Allah bless him and grant him peace, said: ‘Among the worst of people is the two-faced person, who comes to these people with one face and to those people with another.’
Notes and open questions — unreviewed
The Arabic repeats these two groups deictically (“these” and “those”), rather than specifying what the person says to each.
