ولأضلنهم ولأمنينهم ولآمرنهم فليبتكن آذان الأنعام ولآمرنهم فليغيرن خلق الله ومن يتخذ (4:119) بالانجليزي

(4:119) and shall lead them astray, and shall engross them in vain desires, and I shall command them and they will cut off the ears of the cattle, *147 and I shall command them and they will disfigure Allah's creation.' *148 He who took Satan rather than Allah for his guardian has indeed suffered a man-ifest loss.

*147). The reference here is to a superstitious Arabian custom. It was customary among the Arabs that after a camel had given birth to five or ten young to slit her ears and let her go in the name of their deity; they considered it forbidden to put her to any work. Likewise, the male camel that had caused the birth of ten camels was consecrated to some deity. The slitting of ears symbolized this consecration.
*148). To alter God's creation in some respect does not mean changing its original form. If that was meant, human civilization would have to be considered Satanic in its entirety. For civilization consists essentially of man's putting to use the resources endowed by God. Hence the alteration of God's creation, which is characterized as Satanic, consists in using a thing not for the purpose for which it was created by God. In other words, all acts performed in violation either of one's true nature or of the intrinsic nature of other things are the result of the misleading promptings of Satan. These include, for instance, sodomy, birth control, monasticism, celibacy, sterilization of either men or women, turning males into eunuchs, diverting females from the functions entrusted to them by nature and driving them to perform the functions for which men were created. These and numerous similar measures are enacted by Satan's disciples in this world, which amounts on their part, to saying that the laws of the Creator were faulty and that they would like to 'reform' them.
