Sahih Muslim 59a
حَدَّثَنَا يَحْيَى بْنُ أَيُّوبَ، وَقُتَيْبَةُ بْنُ سَعِيدٍ، - وَاللَّفْظُ لِيَحْيَى - قَالاَ حَدَّثَنَا إِسْمَاعِيلُ بْنُ جَعْفَرٍ، قَالَ أَخْبَرَنِي أَبُو سُهَيْلٍ، نَافِعُ بْنُ مَالِكِ بْنِ أَبِي عَامِرٍ عَنْ أَبِيهِ، عَنْ أَبِي هُرَيْرَةَ، أَنَّ رَسُولَ اللَّهِ صلى الله عليه وسلم قَالَ " آيَةُ الْمُنَافِقِ ثَلاَثٌ إِذَا حَدَّثَ كَذَبَ وَإِذَا وَعَدَ أَخْلَفَ وَإِذَا ائْتُمِنَ خَانَ " .
Yahya ibn Ayyub and Qutaybah ibn Sa'id narrated to us—the wording is Yahya's. They said: Isma'il ibn Ja'far narrated to us; he said: Abu Suhayl Nafi ibn Malik ibn Abi Amir informed me, from his father, from Abu Hurayrah, that the Messenger of Allah (peace and blessings be upon him) said: ‘The signs of a hypocrite are three: when he speaks, he lies; when he promises, he breaks his promise; and when he is entrusted, he betrays the trust.’
