Coming back from a journey is indicative of fulfilling the duty required of him and it is indicative of happiness. Undoubtedly the one who returns from a journey will have complete joy. It is also indicative of being safe from harm and attaining blessings, because Allah says:
“So they returned with grace and bounty from Allah. No harm touched them.”
It may also be indicative of repentance on the part of an evildoer,because repentance is coming back(to Allah).
