Narrated Abu Huraira:
حَدَّثَنَا ابْنُ سَلاَمٍ ، حَدَّثَنَا إِسْمَاعِيلُ بْنُ جَعْفَرٍ ، عَنْ أَبِي سُهَيْلٍ، نَافِعِ بْنِ 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 اؤْتُمِنَ خَانَ " .
Allah's Messenger (ﷺ) said, "The signs of a hypocrite are three: Whenever he speaks, he tells a lie; and whenever he promises, he breaks his promise; and whenever he is entrusted, he betrays (proves to be dishonest)".
