Full Sharh — Mishkat al-Masabih 49

English Translation

Abu Huraira reported God's messenger as saying, “There are three signs of a hypocrite.” Muslim added, “Even if he fasts, prays, and asserts that he is a Muslim.” Thereafter both Bukhari and Muslim said, “When he speaks he lies, when he makes a promise he breaks it, and when he is trusted he betrays his trust.”
