وَمَا يَتَّبِعُ أَكْثَرُهُمْ إِلاَّ ظَنّاً إِنَّ الظَّنَّ لا يُغْنِي مِنَ الْحَقِّ شَيْئاً إِنَّ اللَّهَ عَلِيمٌ بِمَا يَفْعَلُونَ

36. “And most of them follow nothing but conjecture: truly, conjecture can be of no avail against the Truth. Verily Allah is well aware of what they do.”

Thus the reason for their being misled and misguided is that they follow their own conjectures and their own corrupt speculations. Conjectures will never lead us to the Truth and to Reality. Following conjectures only results in the doing of indecencies. The verse says:

“And most of them follow nothing but conjecture: truly, conjecture can be of no avail against The Truth...”

What is of real value is “knowledge”. Sound conjecture and confidence, if based on proper solid grounds is valuable, i.e. those conjectures deducted from the apparent words of the holy verses (and quotations) derived from the Allah’s commandments which are practiced by Islamic jurisprudents (Fuqaha’) in even the minute details of problems. The verse says:

“…Verily Allah is well aware of what they do.”

However, conjectures in the realm of ideas, if they are rooted in pursuing the vain way of one’s ancestors or fanaticism based on ignorance are groundless, and hence, are of no avail.
