[And said], "If you do good, you do good for yourselves; and if you do evil, [you do it] to yourselves." Then when the final promise came, [We sent your enemies] to sadden your faces and to enter the temple in Jerusalem, as they entered it the first time, and to destroy what they had taken over with [total] destruction.
[Then Allah said], "It is expected, [if you repent], that your Lord will have mercy upon you. But if you return [to sin], We will return [to punishment]. And We have made Hell, for the disbelievers, a prison-bed."
And We have made the night and day two signs, and We erased the sign of the night and made the sign of the day visible that you may seek bounty from your Lord and may know the number of years and the account [of time]. And everything We have set out in detail.
