The reason for preparing the book Ramadaniyat al-Muslimeen is that this topic requires long pauses in its presentation and treatment. I preferred the author to write a letter on an aspect of this topic addressed to the Muslim sister for several considerations, including: She is half of the community, and she is able to fix some of the flaws due to her affection and her position between husband, father, son and sister, and out of a desire for reform and advice, this brief message was compiled.
