The Messenger of Allah [SAW] said: "The signs of the hypocrite are three: When he speaks, he lies; when he makes a promise he breaks it; and when he is entrusted with something, he betrays (that trust)."
أَنَّ رَسُولَ اللَّهِ ﷺ قَالَ آيَةُ النِّفَاقِ ثَلَاثٌ إِذَا حَدَّثَ كَذَبَ وَإِذَا وَعَدَ أَخْلَفَ وَإِذَا اؤْتُمِنَ خَانَ
