“...Even though they (the two) never taught anyone without saying: 'We are only a trial for you, therefore do not disbelieve '..." In short, when these two angels appeared in the society, sorcery was in fashion among those people and a popular item in their marketplace. At that time, most of the people were captured in the grips of sorcerers.
The two angels taught people the ways in which they could counter the effects of such wicked practices (the witchcraft) of the sorcerers as an art of self-defense. But learning this art demanded, firstly, that they learn about the magic itself. So, in order to be able to negate sorcery, they initially had to learn sorcery itself, and the ways in which it might work effectively, as good skillful magicians. But Jewish mischief mongers took this matter as a means for spreading sorcery more and more.
They expanded it so vastly that they accused the Divine prophet, Solomon (as), of sorcery and said that if nature, or even Jinns and humans, obeyed him (as), it was merely the effect of sorcery. Yes, this is the common habit of the vicious: to accuse the great men as being their followers to justify their own school of thought. At any rate, they could not pass this Divine trial successfully and, consequently, failed in keeping the right path, the true Faith.
“...So they learned from these two (magic spells) by which they might cause separation between a man and his wife..." But the Power of Allah is above all these abilities. “...though they cannot hurt anyone (thereby) but by Allah's leave..." “...They learn what harms them and profits them not..." Yes, they altered this divine constructive training.
Instead of utilizing it on the path of improving their society and using it as a means of defense against the witchcraft of the sorcerers, they applied it to doing evil. “...and they surely knew that the buyers of it would have no share of happiness in the Hereafter...." “...And vile was the price for which they sold their own selves, had they but known (this)!
" ************************ They were heedless of their own happiness and of that of the society they belonged to, and were drowned in the whirlpool of blasphemy. "Yet, had they believed (in Allah) and guarded themselves (against evil)… a reward from Allah would have been better, had they but known (this)!
