1. Ubayy ibn Kaʿb reports that the Messenger of God said: ‘Whoever recites Sūrat Wa al-Nāziʿāt, his detainment and questioning on Judgement Day will be [as if he was only being judged] for the duration of a single obligatory prayer, after which he enters paradise.’^{‎[1]Tabrisi, 10/649.}
2. It is narrated from Imam al-Ṣādiq (a) that whoever recites this surah will not pass away except that he is quenched, and God will not resurrect him except that he is quenched, and he will not enter paradise except that he is quenched.^{‎[2]Thawab, p. 121.}

While reading narrations such as these, it is important to remember that such merits and benefits will be awarded to those who sincerely recite these verses and, most importantly, follow their recitation with practice.
