And incite [to senselessness] whoever you can among them with your voice and assault them with your horses and foot soldiers and become a partner in their wealth and their children and promise them." But Satan does not promise them except delusion.
(Verily, you are of those allowed respite till the Day of the time appointed.) (38:80-81). Then Allah warned him and those who follow him among the progeny of Adam about Hell:
(2) Secondly, he had said if he was given respite till the day of Qiyamah, he will mislead the entire progeny of 'Adam, except a few of them. That Allah Ta’ ala has elected to answer in the later verses. He said that the Shaitan will have no control over His sincere servants even if he were to rally his entire forces against them and as for the insincere who fall into his trap, they will meet the same fate as his, all consigned to Hell. When this verse (64) mentions the horsemen and footmen of the Shaitanic army, it does not necessarily mean that the Shaitan actually has combat support in that formation. In fact, this is a manner of referring to the full force and power of the Shaitan. And if the Shaitan does have horsemen and footmen actually, even that too cannot be denied. Sayyidna ` Abdullah ibn ` Abbas ؓ said: Those who come out in support of disbelief and sin, horsemen or footmen, they are nothing but the army of the Shaitan. Now remains the question as to how the Shaitan came to know that he would succeed in enticing and misleading the progeny of 'Adam (علیہ السلام) ، the basis on which he claimed that he will subdue them. There are two possibilities. Perhaps, by looking at the ingredients that went into the making of man, he had gathered that man would be desire-prone and it would not be difficult to entice him successfully. And then, it is also not far out to believe that his very claim was nothing but a bland lie.
As for the sense of: وَشَارِكْهُمْ فِي الْأَمْوَالِ وَالْأَوْلَادِ (and share with them in their wealth and their children - 64), Sayyidna ` Abdullah ibn ` Abbas ؓ said: Wealth and property acquired by false, impermissible and unlawful means or spent on what is haram is the sharing of the Shaitan in it. As for the sharing of the Shaitan in children, it could either be through illegitimacy, or by naming them like disbelievers and polytheists, or by indulging in polytheistic customs to ensure their security, or by taking to Haram sources of income to bring them up.

Tazkirul Quran
Maulana Wahiduddin KhanOn ayahs 62–64
The story of the angels and Satan shows the difference between the believers and the unbelievers. The believers see the truth as truth, therefore they do not find any difficulty in understanding it. They take no time in accepting it, just as the angels did at the time of the birth of Adam. On the other hand, there is another category consisting of those who see the truth in relation only to their own selves. This is how Satan saw the truth—in relation to his own self. Since the command to prostrate himself before Adam appeared to make him a lesser being than Adam, Satan refused to comply. Seen in the context of the challenge given by Satan to God, everyone who ignores the truth because acceptance of the truth would amount to belittling his own position, has fallen a prey to Satan.
