It's Hayati
Week Fifteen: Your Previous Sins Will be Forgiven
Narrated Abu Huraira:
The Prophet (ﷺ) said, "Whoever established prayers on the night of Qadr out of sincere faith and hoping for a reward from Allah, then all his previous sins will be forgiven; and whoever fasts in the month of Ramadan out of sincere faith, and hoping for a reward from Allah, then all his previous sins will be forgiven."

This hadith tells us the importance of Laylatul Qadr and spending the nights in prayer and fasting during Ramadan out of sincere faith. During Ramadan, we aren't just fasting just to say we fasted. We don't pray because we have to. We do these acts of worship for Allah's sake and His sake only.
We don't do it because we have to but because we want to. Allah doesn't need us... we need Him. We need His forgiveness for the sins we commit. We need His help during hard times. The Prophet (peace and blessings be upon him) tells us in this hadith that if we establish our prayers during the nights of Qadr and if we fast during Ramadan out of sincere faith, our previous sins will be forgiven. And those sins will be forgiven by the Almighty. Our one and only Creator.
If we make sincere intentions to worship Allah for His sake and not for the applause of others, then we will be rewarded for it, In Sha Allah.
May Allah accept all of our acts of worship during these last few days of Ramadan. And may He guide us all toward the straight path.
