Logic or philosophy is no knowledge; in fact, true knowledge is that which God Almighty bestows by His mere grace. Such knowledge is a means of developing a deeper understanding of Allah the Exalted and develops a fear of God in the heart. In this regard, Allah Almighty states in the Holy Quran:
اِنَّمَا یَخۡشَی اللّٰہَ مِنۡ عِبَادِہِ الۡعُلَمٰٓؤُا
‘Only those of His servants who possess knowledge fear Allah.’
If knowledge does not increase a person in fear of God, then remember that such knowledge is not such as can further him in cognisance of the Divine.
Trust in God
Trust in God is the hallmark of Islam. A Muslim is one who believes in giving charity and offering prayer. The Christians do not believe in this. Why is this the case? Christians have crafted their own physical god. One of the greatest and most enduring joys of man, which supports him in times of peril, is trust in God. Only Islam teaches, in the true sense, that one must trust in God.
