Source: Tafsir al-Ahlam al-Kabir (Ibn Sirin)
Locusts in a dream are torment and soldiers. If they are cooked or owned, they are wealth and sustenance. If they descend on a town, it is soldiers or strife.
Source: Ta'tir al-Anam fi Ta'bir al-Manam (Al-Nabulsi)
Locusts indicate a rabble. Eating them indicates a small amount of sustenance. Killing them indicates victory over enemies.
Source: Al-Isharat fi Ilm al-Ibarat (Ibn Shahin)
Locusts are interpreted as torment. Whoever sees himself eating them will gain wealth from soldiers.
