Stealing, fornication, cheating, murder, etc. are major sins in Islam; they are fundamental teachings of perennial religion revealed to all prophets from beginning of times. Thus, it is one of ten commandments revealed to Prophet Musa (peace be upon him); the same applies to the Shari`ah revealed to Prophet Muhammad (peace be upon him). Hence, we read in the sources that the Prophet used to take oaths of allegiance from those migrating to Madinah that they shall not steal.

In conclusion, stealing is a major sin in Islam, regardless of time and place.
