Regret

But if bounty comes to you from Allah, he will surely say, as if there had never been between you and him any affection. "Oh, I wish I had been with them so I could have attained a great attainment."

Then Allah sent a crow searching in the ground to show him how to hide the disgrace of his brother. He said, "O woe to me! Have I failed to be like this crow and hide the body of my brother?" And he became of the regretful.

So you see those in whose hearts is disease hastening into [association with] them, saying, "We are afraid a misfortune may strike us." But perhaps Allah will bring conquest or a decision from Him, and they will become, over what they have been concealing within themselves, regretful.

If you could but see when they are made to stand before the Fire and will say, "Oh, would that we could be returned [to life on earth] and not deny the signs of our Lord and be among the believers."

Those will have lost who deny the meeting with Allah, until when the Hour [of resurrection] comes upon them unexpectedly, they will say, "Oh, [how great is] our regret over what we neglected concerning it," while they bear their burdens on their backs. Unquestionably, evil is that which they bear.

And when regret overcame them and they saw that they had gone astray, they said, "If our Lord does not have mercy upon us and forgive us, we will surely be among the losers."

Indeed, those who disbelieve spend their wealth to avert [people] from the way of Allah. So they will spend it; then it will be for them a [source of] regret; then they will be overcome. And those who have disbelieved - unto Hell they will be gathered.

And [He also forgave] the three who were left behind [and regretted their error] to the point that the earth closed in on them in spite of its vastness and their souls confined them and they were certain that there is no refuge from Allah except in Him. Then He turned to them so they could repent. Indeed, Allah is the Accepting of repentance, the Merciful.

And warn them, [O Muhammad], of the Day of Regret, when the matter will be concluded; and [yet], they are in [a state of] heedlessness, and they do not believe.

And [when] the true promise has approached; then suddenly the eyes of those who disbelieved will be staring [in horror, while they say], "O woe to us; we had been unmindful of this; rather, we were wrongdoers."

True sovereignty, that Day, is for the Most Merciful. And it will be upon the disbelievers a difficult Day.

Then if we only had a return [to the world] and could be of the believers... "

But they hamstrung her and so became regretful.

As a reminder; and never have We been unjust.

If you could but see when the criminals are hanging their heads before their Lord, [saying], "Our Lord, we have seen and heard, so return us [to the world]; we will work righteousness. Indeed, we are [now] certain."

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?

And if you could see when they are terrified but there is no escape, and they will be seized from a place nearby.

Have they not considered how many generations We destroyed before them - that they to them will not return?

And indeed, all of them will yet be brought present before Us.

They will say, "O woe to us! This is the Day of Recompense."
