<b>Guidance from the Hadith:</b><br> 1) One should accompany good people, since companionship has an evident impact on the person’s behavior.<br> 2) A person’s faith increases by accompanying the believers and decreases by accompanying the sinners. A companion is a dragger, either to good or evil, and mixing with someone entails resemblance to them.
