Muhammad peace be upon him was known amongst his tribesmen as "Sadiq" the truthful and "amin" the trustworthy before he was named the Last prophet. Even after becoming the last prophet, while he was being persecuted by the people of Makkah for inviting people to Islam, people used to leave their precious belongings with him because they knew that Muhammad would never betray their trust. Atlast, when Muhammad migrated to Medina he made sure that the belongings people had entrusted Jim with were returned to their rightful owners.
