What is the appropriate book for teaching a Muslim who has recently committed to religious observance the obligatory matters of their religion, and is the book "Islam and its Pillars" by Yassin Rushdi suitable for that purpose?

The book is devoid of legitimate texts and documentation, and it contains matters contrary to the Sunnah, such as the dhikr (remembrance of Allah) after concluding the prayer, like the addition: "(O Most Merciful of the merciful, have mercy on us) three times, and on the third time, add: (and pardon us, O Most Generous)," which is among the innovated matters. Also, without evidence is what is mentioned in it regarding the recommendation of saying the adhan (call to prayer) in the right ear and the iqamah (second call to prayer) in the left for a newborn, one who is distressed, or one who is epileptic, and the recommendation of saying the adhan only at the time of fire, war, and behind a traveler. We recommend the book "What a Muslim Cannot Afford to Be Ignorant Of" for its simplicity and its documentation of legitimate rulings.
