Q- Is there any narration with regards to a person who used a comb with teeth missing to cause poverty?
Allamah Saghani (rahimahullah) has declared a narration which states that combing with a broken comb causes seventy doors of poverty a fabrication. The Hadith is not suitable to quote. (Mawdu’atus Saghani, Hadith: 23).
And Allah Ta’ala Knows Best
