And likewise, to many of the polytheists their partners have made [to seem] pleasing the killing of their children in order to bring about their destruction and to cover them with confusion in their religion. And if Allāh had willed, they would not have done so. So leave them and that which they invent.
Shaytan Lured the Idolators to Kill Their Children
Allah says, just as the Shayatin lured the idolators to assign a share for Allah from what He created of agriculture and cattle - and a share for the idols, they also made it seem fair for them to kill their children, for fear of poverty, and burying their daughters alive, for fear of dishonor. `Ali bin Abi Talhah reported from Ibn `Abbas that he commented;
(And so to many of the idolators, their "partners" have made fair seeming the killing of their children...) "They make killing their children attractive to them." Mujahid said, "Idolators' partners among the devils ordered them to bury their children for fear of poverty." As-Suddi said, "The devils commanded them to kill their daughters so that they,
لِيُرْدُوهُمْ
(lead them to their own destruction), and to,
وَلِيَلْبِسُواْ عَلَيْهِمْ دِينَهُمْ
(cause confusion in their religion.)" Allah said,
وَلَوْ شَآءَ اللَّهُ مَا فَعَلُوهُ
(And if Allah had willed, they would not have done so.) meaning, all this occurred by Allah's leave, will and decree, but He dislikes these practices, and He has the perfect wisdom in every decree. He is never questioned about what He does, but they all will be questioned.
فَذَرْهُمْ وَمَا يَفْتَرُونَ
(So leave them alone with their fabrications.) meaning, avoid and abandon them and what they do, for Allah will judge between you and them.

Linkage of Verses
Described in the previous verses were false beliefs of the mushriks of Arabia while the present verses recount their practical errors and ignorant customs. The customs of Jahiliyyah mentioned in these verses are: (1) They took out a portion in the name of Allah from grains and fruits, and some in the name of idols and Jinns. Then, if by chance, some part of what belonged to the portion of Allah got mixed up with the portion reserved for idols, they would let it stay mixed as it was. When the position was the reverse of it, they would take it out and make the portion set for idols even. The excuse was that Allah is need-free. A cut in His share does not harm Him while the partners need it - so, their share should not be decreased. This evil custom was mentioned earlier in verse 136.
(2) The second custom was that they would release animals they called Bahirah and Sa'ibah in the name of idols and said that they were doing it for the pleasure of Allah. Here too, the portion allotted to idols was that the act of worship was intended for them - and the portion allotted to Allah was that they aimed to please Allah.
(3) The third custom was that of killing their female children.
(4) The fourth custom was that they would endow some tillage in the name of idols saying that only men could use its produce. Giving or not giving a share from it to women depended on their will. Women had no right to demand.
(5) They would do the same thing with cattle when they would restrict their use for men only.
(6) They considered the quadruped animals they released in the name of idols as unlawful for purposes of riding or carrying loads.
(7) There were quadruped animals they would specify. Using them at any time, they would not pronounce the name of Allah, neither when milking, nor when riding and nor when slaughtering.
(8) The eighth custom was that they would release animals in the name of idols, naming them as Bahirah or Sa'ibah. When, at the time
of slaughter, the calf came out alive, they would slaughter it as well - but, would take it as lawful for men only; for women, they took it to be unlawful - and if the calf was born still, it was supposed to be lawful for everyone.
(9) Even milk from some animals was considered lawful for men and unlawful for women.
(10) They took reverence for four kinds of animals: Bahirah, Sa'ibah, Wasilah and Hami, as an act of worship.

Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 136–138
Man invents tangible deities because he does not have full faith in the intangible Supreme Being—God. In ancient times polytheists did, however, pay lip service to God, while reserving their real faith for their deities. This was evident from the inequitable way in which they apportioned their sacrificial offerings of grain and livestock to their deities on the one hand, and to God on the other. It was always the deities who were given preference in terms of the quantity and quality of the offerings, and never God. Moreover, when those who in reality are idolaters are ‘worshipping’ God, they devote a part of their prayers to that person, living or dead, whom they idolize. But when they worship the latter, they do not even mention the name of God. They will readily lavish upon a partner that ecstatic devotion which they should reserve for God. In any meeting held to extoll God’s greatness, the majesty and glory of the partner will somehow find a place; but in any meeting held to describe the greatness of the partner, there will be absolutely no mention of the majesty and glory of God. The importance of the ‘partner’ sometimes dominates minds to such an extent that a man will with pleasure sacrifice even his children for it—something which he will not do for the sake of God. All such acts are carried out in the name of God’s religion, but falsely so, because this amounts to attributing to God such precepts as had never been laid down by Him.
