Mohammad bin Yaqoub states in Al-Kafi Book: Mohammad bin Muslim reported from Imam Abou Jaa'far (Pbuh) that he said: "Allah honored the believers with Al-Jom'a Chapter and so the Messenger of Allah (Pbuhp) used to recite as glad tidings for them. Allah disparaged the hypocrites with Al-Munafiqoun Chapter. These two chapters shouldn’t be neglected. He who neglects them isn’t considered to be praying."
Ibn Babawaih states in Thawab Al-A'amal Book: Mansour bin Hazim reported from Imam Abou Abdellah (Pbuh) that he said: " It is an obligation on every believer if he was a follower of us to recite on Friday Eve Al-Jom'a and Al-A'ala Chapters and in the noon prayer Al-Jom'a and Al-Munafiqoun chapters. When one does that, he is considered as if he worked the work of the Messenger of Allah (Pbuhp) and his reward given by Allah is heaven."
Al-Tabrasi states in Majm'a Al-Bayan Book: The Messenger of Allah (Pbuhp) said : "He who recites Al-Jom'a Chapter is given the rewards of ten righteous deeds multiplied by the count of all who came of Muslims for payer on Friday and who didn’t come."
Khawas Al-Quran Book:The Messenger of Allah (Pbuhp) said: "For he who recites this chapter Allah will give him rewards of ten righteous deeds multiplied by the count of all who gathered of Muslims on Friday. He who recites it in every day or night shall be safe from what he fears and he shall be protected from every worrying matter."
Khawas Al-Quran Book:The Messenger of Allah (Pbuhp) said: " He who recites it constantly earns a great reward and he shall be safe from what he fears and protected from every worrying matter."
Khawas Al-Quran Book: Imam Sadiq (Pbuh) said: "He who recites it constantly day and night shall be safe from the lures of demons and he shall be forgiven for what he does of that till the next day."
