وقالوا هذه أنعام وحرث حجر لا يطعمها إلا من نشاء بزعمهم وأنعام (6:138) بالانجليزي

(6:138) They say: 'These animals and these crops are sacrosanct: none may eat of them save those whom we will' - imposing interdictions of their own contriving. *111 And they declare that it is forbidden to burden the backs of certain cattle, and these are the cattle over which they do not pronounce the name of Allah.  *112All these are false fabrications against Allah, *113 and He will soon requite them for all that they fabricate.

Tafseer Abu-al-A'la Maududi

Page 146 English Traditional

*111). There was a practice among the people of Arabia whereby they used to consecrate certain animals and farms to certain shrines, and at offerings at certain altars. These consecrated offerings could not be used by everybody. An elaborate code laid down what kind of offering could be used by what kind of people. God not only judges such practices to be polytheistic, but also censures them as man-made innovations. God was the master of all that they had consecrated as offerings to the deities. He had neither encumbered human beings with the need to make any of those offerings and consecrations nor imposed those restrictions on what they might consume. These were the wilful inventions of headstrong and rebellious people who attributed to themselves the authority to make laws as they pleased.
*112). Traditions indicate that there were certain ritual offerings, and that on certain occasions animals were consecrated for sacrifice at which it was deemed unlawful to pronounce the name of God. It was also prohibited to ride such animals during the Pilgrimage, since at that time the pilgrim pronounced the name of God when he recited the formula: Labbayk Allahumma Labbayk. Every care was taken not to pronounce the name of God at the time of milking, mounting, slaughtering and eating of such animals.
*113). Even though those rules had not been laid down by God, people followed them under the false impression that they had been prescribed by Him. They could not adduce any injunction from God in support of such a belief, and all that they could claim was that it was an integral part of their ancestors' way of life.
