The word Hamad is one of the key words in the field of devotional concepts in the Holy Quran. This word has been interpreted as praise and praise in Arabic dictionaries and interpretations of the Quran in terms of its explicit

Since the Qur'an is a multi-dimensional and multi-layered book, and every concept in it can be examined and used from multiple angles and dimensions, it is therefore necessary to have a comprehensive look at the concepts of this infinite divine sea. Concepts that are effective and decisive in all aspects and dimensions of a person's worldly and hereafter life and clear and smooth the way ahead. Until now, each of the scholars of the Qur'an has interpreted the Qur'an from a different angle; Despite honoring their efforts and efforts, each one of them has neglected aspects of the sublime and practical concepts of the verses, and this means losing a huge part of deep and subtle knowledge that can arrest people. Our goal in this article is to show that the best interpretation method for Quranic words and verses is comprehensive interpretation. A comprehensive interpretation that can deal with the verses from all aspects; And we have tried to prove this by researching the word praise in the interpretation of the verse "Alhamdulillah Rab Al-Alamin" from the point of view of 18 Shia and Sunni commentary books. Various books of Arabic and Persian interpretation (Shia and Sunni), each of which has performed interpretation with a specific tendency and method, have been examined and nearly 150 points and narrations have been extracted about this verse; And after 
comparing each type of interpretation separately with a comprehensive view, the result provides the best method for interpreting the Qur'an, which is indeed a comprehensive interpretation
