Islamic Interpretation of Dreams (Ibn-i Sirin):
A sparrow or a hawk in a dream represents an ignorant and unjust ruler. Both command lesser controlling domains than the eagle. Holding a sparrow or a hawk in a dream means that one will capture a thief.
If one sees himself producing a sparrow or a hawk out of his urethral canal, it means that he will bore a son who will possess courageous and frivolous character. Holding a sparrow in a dream also means choosing a community of elders and volunteering ones services.
