Spend your nights praying sincerely out of faith with hope for a reward from Allah .

This hadith is about the power of prayer during the holy month of Ramadan and on Laylatul Qadri. It was narrated by Abu Hurairah that Prophet Muhammad said that whoever spends their nights in prayer during these two occasions out of faith and with the hope for a reward, their previous sins will be forgiven. This means that if we pray sincerely during these times, Allah will forgive us for any wrongdoings we have done before. It is important to remember to always have faith in Allah when praying so He can accept our prayers. Additionally, it is important to keep in mind that even though Allah may forgive us for our past mistakes, it does not mean we should continue making them; rather, it should motivate us to strive harder towards righteousness so as not to repeat them again.
