1. Imam as-Sadiq said: Whoever recites Surah Kafiroon and Surah Tauheed in one of his obligatory prayers, Allah grants forgiveness for him, for his parents and for his children, and if his name is written in the register of unfortunate and disobedient persons, then after erasing it He writes in it the register of virtuous and happy people and Allah would grant him the death of a martyr and raise him on the Day of Judgment with the martyrs.
