Omar
If one sees him frowning in a dream, it means that Omar is calling for justice, commanding what is good and forbidding what is evil. If there is a drought in a town and one sees Omar in a dream, it means that rain will fall and be a blessing for that land. If there is tyranny in that land and one sees Omar in his dream, it means that justice will prevail. If Omar hits someone with a stick, or warns him, or threatens him in a dream, it means that one must renounce the course of his current actions or deviation from Allah's path, or perhaps that someone in authority or a scholar will persecute him. If one sees himself being Omar in a dream, or if he wears one of his garments in a dream, it means that he will be awarded honor, a dignified status, or die as a martyr.
Dream interpreter: Ibn Sirin
