This is a handbook prepared by Imam Hassan al-Banna for his members of the organization with the aim of cultivating the culture of Tazqiyyah, in which the whole of life is organized by the remembrance of Allah.

It codifies the Dhikr to be recited daily.
He advises his members to recite it alone or in groups, at any convenient time in the morning and evening.
Actually, It is a directive to the members of the Muslim Brotherhood, but it can be followed by any Muslim.
It is hoped that this handbook will help you to memorize Allah day and night and to make Dhikr a part of your life to cultivate your mind and deeds.
