19. Ali ibn Muhammad has narrated from Sahl ibn Ziyad from Ahmad ibn ‘Ubdus from Muhammad ibn Zawiyah from abu Ali ibn Rashid who has said the following: “I said to abu al-Hassan, ‘Alayhi al-Salam, ‘May Allah keep my soul in service for your cause, you have written to Muhammad ibn al-Faraj telling him that the most excellent recitation in obligatory Salah (prayer) are chapters 97 and 112 of the Holy Quran. I feel uneasy reciting them in morning Salah (prayer).’ The Imam said, ‘You should not feel uneasy to recite them, by Allah, excellence is in reciting these two chapters.’” (Ahadith 12-19 are best explained in the form of fatwa.)
