Miracles of Quran: Pairs. Scientists say that man’s brain can't perform more than two tasks simultaneously. When man performs two tasks together, the left hemisphere of the brain performs one task while the right hemisphere performs the other one.
Thus, man tends to choose the simpler choice which is to choose between two things. Miraculously, the holy Qur’an is in absolute harmony with the instinct of man for we always choose between two things such as the good or the bad, right or wrong, guidance or delusion, heaven or hell, generosity or stinginess, justice or oppression, good or evil, etc. Other religions and human beliefs on the other hand offer man multiple options in a manner that contradicts with their instinct. Allah, the exalted, therefore, says in the holy Qur’an:
فَأَقِمْ وَجْهَكَ لِلدِّينِ حَنِيفًا فِطْرَتَ اللَّهِ الَّتِي فَطَرَ النَّاسَ عَلَيْهَا لَا تَبْدِيلَ لِخَلْقِ اللَّهِ ذَلِكَ الدِّينُ الْقَيِّمُ وَلَكِنَّ أَكْثَرَ النَّاسِ لَا يَعْلَمُونَ
“So set thou thy face steadily and truly to the Faith: (establish) Allah's handiwork according to the pattern on which He has made mankind: no change (let there be) in the work (wrought) by Allah: that is the standard Religion: but most among mankind understand not." Rum: 30:30
