What does « Ruse / Deception » mean in the Quran?

And [remember, O Muhammad], when those who disbelieved plotted against you to restrain you or kill you or evict you [from Makkah]. But they plan, and Allah plans. And Allah is the best of planners.

And when We give the people a taste of mercy after adversity has touched them, at once they conspire against Our verses. Say, "Allah is swifter in strategy." Indeed, Our messengers record that which you conspire

So when she heard of their scheming, she sent for them and prepared for them a banquet and gave each one of them a knife and said [to Joseph], "Come out before them." And when they saw him, they greatly admired him and cut their hands and said, "Perfect is Allah! This is not a man; this is none but a noble angel."

That is from the news of the unseen which We reveal, [O Muhammad], to you. And you were not with them when they put together their plan while they conspired.

Then is He who is a maintainer of every soul, [knowing] what it has earned, [like any other]? But to Allah they have attributed partners. Say, "Name them. Or do you inform Him of that which He knows not upon the earth or of what is apparent of speech?" Rather, their [own] plan has been made attractive to those who disbelieve, and they have been averted from the way. And whomever Allah leaves astray - there will be for him no guide.

And those before them had plotted, but to Allah belongs the plan entirely. He knows what every soul earns, and the disbelievers will know for whom is the final home.

And they had planned their plan, but with Allah is [recorded] their plan, even if their plan had been [sufficient] to do away with the mountains.

Those before them had already plotted, but Allah came at their building from the foundations, so the roof fell upon them from above them, and the punishment came to them from where they did not perceive.

Then, do those who have planned evil deeds feel secure that Allah will not cause the earth to swallow them or that the punishment will not come upon them from where they do not perceive?

And be patient, [O Muhammad], and your patience is not but through Allah. And do not grieve over them and do not be in distress over what they conspire.

And they planned a plan, and We planned a plan, while they perceived not.

Then look how was the outcome of their plan - that We destroyed them and their people, all.

And grieve not over them or be in distress from what they conspire.

Those who were oppressed will say to those who were arrogant, "Rather, [it was your] conspiracy of night and day when you were ordering us to disbelieve in Allah and attribute to Him equals." But they will [all] confide regret when they see the punishment; and We will put shackles on the necks of those who disbelieved. Will they be recompensed except for what they used to do?

Whoever desires honor [through power] - then to Allah belongs all honor. To Him ascends good speech, and righteous work raises it. But they who plot evil deeds will have a severe punishment, and the plotting of those - it will perish.

[Due to] arrogance in the land and plotting of evil; but the evil plot does not encompass except its own people. Then do they await except the way of the former peoples? But you will never find in the way of Allah any change, and you will never find in the way of Allah any alteration.

So Allah protected him from the evils they plotted, and the people of Pharaoh were enveloped by the worst of punishment -

And they conspired an immense conspiracy.
