Al-Najm: Merits
From Ubayy ibn Kaʿb, that the Prophet said: ‘Whoever reads Sūrat al-Najm will be given ten times the goodly reward of the number of people who believed in Muhammad (s) and who opposed him.’1
From Yazīd ibn Khalīfah, that Imam al-Ṣādiq (a) said: ‘Whoever continuously recites [Sūrat] al-Najm every day or every night will live honoured amongst the people and will be missed and loved amongst them.’2
Without a doubt, these rewards are for the one who has understood the message of the surah and has lived by it.3
