The Prophet (s) said “I swear by the Lord in whose hands my life is that you cannot attain paradise and eternal bliss unless you become true believers and you cannot become true believers unless you love one another. May I guide you towards an act as a result you will develop mutual friendship and love?” Thereupon he said “Greet one another open heartedly.”[1]
