Harvesting crops in their season indicates goodness, sustenance, and justice. Out of season, it indicates war, death, or strife.
Source: Ta'tir al-Anam fi Ta'bir al-Manam (Al-Nabulsi)
The harvest indicates the end of one matter and the beginning of another. For a merchant, it is profit, and for the sick, death.

The harvest is interpreted as spoils and wealth. Whoever sees himself harvesting another's crops will be afflicted with harm.
