Narrated Abu Huraira (RA): Allah's Messenger (SAW) said: "Whoever establishes prayers during the nights of Ramadan faithfully out of sincere faith and hoping to attain Allah's rewards (not for showing off), all his past sins will be forgiven."
(Bukhari)
Do not lose hope. It may feel like your heart is so shattered that the pieces can’t be put back together. But Allah will repair you better than you were before. Trust Him!
