What is the significance of fasting during Ramadan and praying during Lailat-ul-Qadr, according to Prophet Muhammad (saw)?
 Abu Huraira reported Allah's Messenger (may peace be upon him) as saying:                      He who observed the fasts of Ramadan with faith and seeking reward (from Allah), all his previous sins would be forgiven, and he who observed prayer on Lailat-ul- Qadr with faith and seeking reward (from Allah), all his previous sins would be forgiven.
