From the book:
The Dhikr of Allah is the soul and the life of the hearts and the cause of its development and strength; and abundant rewards and immense good in this world and the next-whose count cannot be enumerated except by Allah are a direct result of it (i.e., Dhikr)
Indeed, the Dhikr of Allah (سُبْحَانَهُ وَتَعَالَى) is the symbol of happiness and the path of success in this life and the next; rather all good, happiness, delight, pleasure and tranquility in this world and the hereafter is dependent on the actualization of the Dhikr of Allah ( سُبْحَانَهُ وَتَعَالَى). Indeed, all of the legislation and acts of obedience in totality were legislated to establish the Dhikr of Allah . Hence what Allah ( سُبْحَانَهُ وَتَعَالَى) has legislated for his servants from Salah, fasting, Hajj and other than that from the acts of obedience is solely for establishing the remembrance of Allah
