"The master of (Or the best way to) seeking forgiveness is for the servant to say;
O Allah subhanahu wa ta'ala, you are my Lord. There is nothing worthy of worship except you. You created me, and I am your slave, I try my best to fulfill your promise and the covenant. I seek refuge in you from the evil, which I have done. I admit to you, your favors upon me, and I admit to you my sins. So forgive me, verily none can forgive sins except you."
