Ramadhan is the month of Forgiveness
In the name of Allāh, the Most Gracious, the Most Merciful;
All the praise and Thanks are due to Allāh, the Lord of the al-ā’lamīn. I testify that there is none worthy of worship except Allāh, and that Muhammad, sallallāhu alayhi wa sallam, is His Messenger.
There are various Prophetic sayings which state that the various types of worship in Ramadhan are a means to seek forgiveness from Allah Subhanahu Wa Ta'ala. The Fasting, the Solatul Tarawih (Qiyam of Ramadhan) , and praying the Tahajjud in the Honored Night with faith are all the means of seeking Allah’s forgiveness.
“Whoever fasts the month of Ramadhan, believing in God and hoping for His reward, all his previous sins will be forgiven?” (Sahih Al-Bukhari)
“Whoever stands the night in prayer in Ramadhan believing in God and seeking His reward, all his previous sins will be forgiven.” (Sahih Al-Bukhari)
“Whoever stood in prayer in the Honored Night, believing in God and hoping for His reward, all his previous sins will be forgiven.” (Sahih Al-Bukhari)
Ramadhan in general is a month of savior from the Fire:“God chooses who will be saved from the Fire (in Ramadhan), and that is every night.” (Al-Tirmidzi)
