The Essence of the Holy Qur’an
And do not pursue that of which you have no knowledge. Indeed, the hearing, the sight and the heart about all those [one] will be questioned (by Allah). And do not walk upon the earth proudly. Indeed, you will never tear the earth, and you will never reach the mountains in height.
(Surah No.17, Bani Israil, Verse No.36-37)
Don’t be guided by conjecture rather than knowledge:
The purpose of verse no. 36 is that people should be guided by knowledge rather than conjecture both in their individual and collective lives. In an Islamic society, this directive found its reflection in ethics and law, in politics and administration, and in arts, sciences and education; in short, in all spheres of human life.
Do not rely on guesswork:
This perspective ensured that human thought and action were made safe from the many evil consequences which ensure from relying on guesswork and conjecture instead of knowledge. Therefore, in matters of conduct and behavior people are asked to abstain from entertaining misgivings about others and to avoid leveling unfound charges against both individuals and groups.
Islamic law also prohibited both the consigning of people to prison or their manhandling merely on the grounds of suspicion.
Allah instructed the Muslims in the verse no. 37 that their manners and behavior, their dress, their homes, their means of transport, and their general mode of conduct with others were all distinguished by humility, self-negation and a detached attitude towards this worldly life.
