Critical thinking is a very important intellectual tool that could help a person form arguments, determine the credibility of sources, analyse presumptions or make decisions in various contexts. Hence, this study intended to examine the Western and Islamic critical thinking concepts as well as its significance according to the al-Quran and the views of scholars. The library research method was used extensively for collecting and analysing data, which was sourced from literature by philosophers, psychologists and Islamic scientists, especially those involved in the cognitive field. The conceptual framework was built using the content analysis method. According on the analysis, the importance of Islamic critical thinking based on the al-Quran and views of scholars in the cognitive field were extensively elaborated to assist in the practice of Islamic critical thinking. The study found similarities and differences between Islamic and Western critical thinking. The similarities are from the rational utilization aspect and the difference is from the value of truth aspect, whereby Islamic critical thinking accepts divine deliverance (wahyu) as the main source of reference when thinking so that the product of thinking eventually becomes the absolute truth. Hence, the major significance of Islamic critical thinking is to enhance the faith (iman) and piousness (takwa) towards Allah SWT by contemplating and examining nature. At the same time, critical thinking helps a person to face contemporary challenges and solve problems related to every aspect of life. Moreover, critical thinking activities are greatly demanded in Islam so that the mind bestowed by Allah SWT is not neglected and is used properly without transgressing HIS divine deliverance (wahyu).

The information done by scholars leaves a legacy of connecting scholars' knowledge brochures. The authors' processing of science gives these works their valuation. Acceptance of scholars' remaining works can be seen in studies as well as reviews from scholars. The Book of Hujjah Allah al-Balighah by Shah Wali Allah al-Dihlawi is one of the book that the studies focus on to explore his knowledge presented through the scripture. These book are more than two-hundred-year-old and it's a treasure of Islamic knowledge that can be studied in a range of methods. As a result, the purpose of this study is to introduce al-Dihlawi as a multidisciplinary Islamic scientist and to explain the methodology he employed to compile his writings. By researching the study book and related writing resources, this qualitative study uses the literature methodology. The outcomes of the studies revealed that al-Dihlawi, through the Hujjah Allah al-Balighah book, not only explained the discussion of the wisdom of the zahir of every worship but also concentrated on the inner secrets on the contrary. He described asrar al-shariah, or the secrets of Shariah, in terms of analyzing the meaning of decisions made. Scholars have debated this issue in the context of maqasid al-shariah. Given its prolonged debate and continued relevance, this book is suitable to be highlighted in society. The contribution left by al-Dihlawi became one of the successors to Islamic knowledge for generations after him
