Human reason ?

It is a Muslim’s duty to submit to the laws of Allah believing firmly that they are for his benefit whether he or she can see an obvious value in them or not. It is not necessary for Muslims to demand a logical explanation for every aspect of Islaam before applying it. But, it is their right to be sure that it is not a cultural practice or innovation, but an actual command from the Prophet صلى الله عليه و سلم himself. ‘Alee ibn Abee Taalib said, “If the religion (of Islaam) were based simply on (human) reason, the bottom of the socks (Khuff) should be wiped (during Wudoo) and not the tops, however, I saw Allaah’s messenger wipe the tops of his socks and not the bottoms.”
