A man came to the Prophet (peace and blessings be upon him) and said: O Messenger of Allah! Which supplication is the most virtuous? The Prophet (peace and blessings be upon him) said: "Ask Allah for forgiveness and well-being in this world and the Hereafter." Then he came the next day and said: O Prophet of Allah! Which supplication is best? The Prophet (peace and blessings be upon him) said: "Seek pardon and well-being from Allah in this world and the Hereafter. If you are granted well-being in this world and the Hereafter, then surely you have succeeded."
