Yes, Allah observes the regrets of humans regarding their sinful actions and lack of faith.
In the Holy Quran, the topic of regret and sorrow is discussed in several verses. Allah says in Surah Al-Mu'minun, verse 37: 'People will regret on the Day of Judgment due to their lack of faith in God and their sinful actions.' This regret primarily arises from neglecting the remembrance of God and ignoring His commands. In Surah Az-Zumar, verse 56, it states: 'So no one should say: I wish I had been with the messengers.' These verses illustrate that regret will not solely stem from worldly matters, but also from a lack of close connection with God and failure in spirituality. God reminds His servants in other verses that while He is aware of their condition, they themselves must take steps towards the truth. In fact, regret is a sign of human awareness that can be transformed by repentance and returning to God. Allah has mercy on those who repent and provides them with His blessings. Therefore, the regrets of humans are not only observable by God but can also lead to positive changes in their situations through adherence to divine commands.
Indeed, nothing benefits those who have not believed in Allah, and have gathered wealth; they are in great loss.
And let no one say: 'I wish I had been with the messengers.'
One day, a man named Ali decided to move forward in life with goodness. He remembered the verses of the Quran and thought about how to make the most of his life. Every day, he tried to get closer to God through prayers and good deeds. Ali realized that the regrets of people in today's world stem from being distant from God and forgetting His verses. He felt he had found nourishment for his soul and reduced regrets and sorrows with his love and kindness towards God and humanity.
