It has been reported from Imam al-Ṣādiq (a): ‘Whoever recites this chapter in his recommended prayers, God will resurrect him on the Day of Judgement whilst his face is illuminated and smiling and his eyes are filled with joy, until he enters paradise.’ In another narration from the Holy Prophet it has been narrated: ‘Whoever recites Sūrat al-ʿAṣr, God forgives him and he is like the one who has advised others to truth and patience.’
It must be noted, however, that this type of reward and position is for one who has implemented in his life the four principles which the surah mentions and has not merely verbally recited the verses.
