[Pooya/Ali Commentary 73:19] The Quran is a reminder to man that he should follow the right path to earn the mercy and grace of Allah. Aqa Mahdi Puya says: Verses 1 to 19 were revealed in the early period of the Holy Prophet's ministry. Verses 10 to 19 refer to the period when opposition to his preaching was started. Verse 20 refers to the period when jihad was ordained. The Ahl ul Bayt in particular and the Muslims in general have asserted this chapter to be complete and wellarranged, so it can be recited in the prayers.
