Surah al-Ahzab verse 66
“On the day (when) their faces will be turned upside down in Hell, they will say, “O, that we used to obey Allah and obey (also) the Messenger.”
This sentence was uttered by people who during their lifetime neglected the commands of Allah and His Messenger. Even though they actually know, they are reluctant to obey Allah’s commands. So when Allah Ta’ala turns his face in hell, they say if he had obeyed Allah and His Messenger then of course they would not have been tormented like that.
These are the sentences of regret on the Day of Resurrection that are enshrined in the Qur’an. It’s a meaningless regret. Because no matter how big the regret is expressed, it certainly will not be able to change the situation on the Day of Resurrection.
Therefore, while we still have the opportunity, let’s improve ourselves to be even better. Let’s compete to save good deeds as provisions in the hereafter before the day of regret comes. May be useful.
