Ramadan: The Holy Prophet (peace and blessings of Allah be upon him) is reported to have said in the Hadith: “Ramadan is a month whose beginning is mercy, whose middle is forgiveness, and whose end is freedom from the Fire.”
According to the declaration that the second 10 days of Ramadan are the ten days of forgiveness, the following prayer should be said:
I confess my sins to my Lord and ask Him for forgiveness.
