It is narrated from Hazrat Abu Huraira (may Allah be pleased with him) that the Noble Prophet (peace and blessings be upon him) said: There are some signs of hypocrites by which they are recognized: their greeting consists of words of curse, their food is obtained by plundering, their spoils of war are acquired through dishonesty, they remain near the mosques yet are far (from them), even when coming for prayer they turn their backs to it, they are arrogant, they do not befriend anyone nor does anyone befriend them, at night there is the sound of bamboo and during the day there is noise and commotion.
