Exegesis of the saying of Allah the Exalted: "Forgiveness, our Lord, and to You is the final return."

The Shaykh : This is why we pray, and the first thing we begin with after the prayer is to say, "I seek forgiveness from Allah, I seek forgiveness from Allah, I seek forgiveness from Allah," because a person is never free from defects. Here they said: Then they said: fearing that there might be some deficiency in what they obeyed Allah in.

To You is the final return in the management of our affairs, for You manage our affairs? To You is the final return on the Day of Resurrection? Does this include these three and others whose return is to Allah? Or is it specific to the Day of Resurrection?
The answer: It includes them.
