Ramadan is the Month of Blessings and Forgiveness
Narrated Abu Hurairah: Allah's Messenger (ﷺ) said,
مَنْ صَامَ رَمَضَانَ إِيمَانًا وَاحْتِسَابًا غُفِرَ لَهُ مَا تَقَدَّمَ مِنْ ذَنْبِهِ
"Whoever observes fasts during the month of Ramadan out of sincere faith, and hoping to attain Allah's rewards, then all his past sins will be forgiven."
Sahih al-Bukhari (38)
