Seeing a sickle in your dream may indicate that you want to cut away some old or unnecessary aspects of your life. It can signify changes, new beginnings, or a desire to free yourself from past relationships. Since the sickle is commonly associated with agriculture, it may also symbolize new opportunities or productivity in your work. This dream encourages you to focus on achieving your goals.
From Imam Muhammad Ibn Seerin's Dictionary of Dreams According to Islamic Inner Traditions â entry "Sickle" (page 389).
~iddiqi.in: He is the arc angel ,Saddiqiin, upon whom be peace, who is in charge of interpreting the meaning of dreams and visions, or giving explanatory parables drawn from the heavenly Preserved Tablet. Seeing him (uwbp) in a dream represents glad tidings, festivities, fulfilling promises, recognizing the inevitability of death, enjoying life, travels, coming home, marriage, children, a high ranking appointment, gaining power, victory, or perhaps defeat and humiliation. Whatever this blessed angel of dreams gives or tells will take effect as it is, for he is in charge of such a duty. The arc angel S.addiqiin in a dream also represents the speaker of the house, the translator of the palace, the one who delivers the royal decree and knows the inner secrets. Seeing him in a dream also represents piety, medicine, clarity, perspicacity, transparency of one's vision, the school teacher who keeps looking at the blackboard, the librarian, an official speaker, logs, or books.
Note: Islamic dream interpretation depends on the dreamer's circumstances and state. This is a general guide drawn directly from the source book.
