One of the great achievements during Ramadan is repentance
One of the great achievements of the month of Ramadan is repentance and returning to Allah the Exalted. In the holy dua of Abu Hamza Thumali, we read, "Let us gather around Mustafa and achieve the position of returning to you". We ask God to help us achieve the position of repentance so that we can return to Him and return from deviant, bad and indecent actions, thoughts and conducts.
In the farewell dua of the auspicious month of Ramadan, Imam Sajjad (a.s.) says to the God of the world, "You are One Who opened a door for Your servants so that they can return to You and You named this door repentance" [Sahifa al-Sajjadiyya, Dua 45]. He says to God that He opened this door for us so that we rush towards His forgiveness and benefit from the blessing of His forgiveness and mercy.This door is the door of repentance. It is a window to the pure view of divine forgiveness.
