(25) باب بَيَانِ خِصَالِ الْمُنَافِقِ
It is reported on the authority of Abu Huraira that the Messenger of Allah (may peace and blessings be upon him) said:
Three are the signs of a hypocrite: when he spoke he told a lie, when he made a promise he acted treacherously against it, when he was trusted he betrayed.
