Islamic Interpretation of Dreams (Ibn-i Sirin):
(The prophet Ismail, son of the prophet Abraham, upon both of them be peace.) If one sees him in a dream, it means that he will gain clarity of speech and preside over his colleagues. He also may build a mosque, or participate in such a project.
It also means that someone will make a promise and be truthful about fulfilling it.
Ifone sees Ismail in a dream, it means that he may suffer at the hands of his father, then God Almighty will relief him from such sufferings or pain.
