The method by which the Muslim acquires knowledge and thought is critical in determining the impact of the Islamic thoughts upon the individual. If the method of acquiring knowledge was correct and based upon research, profound thinking, and analysis (as Allah (swt) ordered) then it will produce effective results, and such a person will turn into an ideological person who thinks in a distinct manner. Allah (swt) orders the human being to think about many aspects of His Creation in a profound and enlightened manner:

"Verily! In the creation of the heavens and the earth, and in the alternation of night and day, there are indeed signs for men of understanding." [TMQ 3:190] "Do they not then consider the Qur’an carefully? Had it been from other than Allah, they would surely have found within it many contradictions." [TMQ 4:82] "Tell Me! The water that you drink — is it you who causes it to come down from the rain clouds, or are We the Cause for it to come down?" [TMQ 56:68-69] "He is created from a fluid poured forth — proceeding from between the back bone and the ribs." [TMQ 86:6-7] "Do they not look at the camels, how they are created? And at the heaven, how it is raised? And at the mountains, how they are rooted and fixed firm? And at the earth, how it is spread out?" [TMQ 88:17-20] In all of these ayahs, Allah directs the human being to think and analyze in order to build the Aqeedah of Islam within him through a definite conviction.
