What is "al-masad"

Sūrat al-Masad (, meaning "The Palm Fiber") is the 111th chapter ( Sura) of the Quran with 5 verses. Verse 1 mentions one of Muhammad's adversaries named Abu Lahab. This surah takes its name from verse 5 in which the phrase “ḥablun min masad” (meaning “a rope of palm fibre”) occurs that mentions the palm fibre rope that in hellfire shall be twisted around the neck of the wife of Muhammad’s uncle, who bitterly opposed Islam; for she took great pride in wearing an ostentatious necklace she became known for and would slip by night to strew thorns and prickly plants in Muhammad’s path to injure his feet.
