Islamic Interpretation of Dreams (Ibn-i Sirin):

(Butter; Cheese shop; Ghee; Milk products) A grocer selling any milk products represents a gnostic, a man of great knowledge, a well known man of piety and good deeds who shares his knowledge, wisdom and wealth with others.

Seeing a grocer in a dream also could mean marriage for an unwed person with a wealthy and beautiful woman.

A grocer also represents a rich person who sustains those who live near him or follow him.
