Ibn Babawaih states in Thawab Al-A'amal Book: Safwan Al-Jammal reported from Imam Abou Abdellah (Pbuh) that he said: "He who recites Al-Mutaffifeen Chapter in regular prayers, Allah grants him safety from fire. It neither sees him nor he sees it. His body will not pass by hell and hell will not be judged on Resurrection Day."
Al-Tabrasi states in Majma' Al-Bayan Book: The Messenger of Allah (Pbuhp) said: "He who recites it, Allah makes him drink from the nectar of heaven on Resurrection Day."
Khawas Al-Quran Book: The Messenger of Allah (Pbuhp) said: "Allah makes him drink the nectar of heaven he who constantly recites this chapter. If it was recited on a store Allah guards it from every harm."
