Shab-e-Qadr, also called as Laylatul Qadr, Night of Power, and Night of Decree, is considered one of the holiest or sacred nights in the Islamic Calendar and is observed by all Muslims worldwide during the last ten days or third Ashra of Ramazan. As per Islamic Belief, the Holy Quran was first sent down from heaven to the world and it is a precious night when the first verses of the holy book were revealed or introduced to the Prophet Mohammad. It is believed that Angel Jibril (Gabriel) delivered the Quran to the Prophet Mohammad, which may be occurred on this night. It is also believed that Prophet Mohammad became the Prophet and Messenger of Allah on this night, thus Laylatul Qadr (Shab-e-Qadr) is also called as the Night of Power.

As per Islamic Belief, all the sins and mistakes of the individual are forgiven, and wishes or prayers are accepted by God (Allah). Thus, it is believed that the night of Shab-e-Qadr is more sacred, or blessed, or holiest than a thousand months or nights and is observed by all Muslims across the world with huge devotion to Almighty Allah. Shab-e-Qadr is a night of special prayer (Namaz), spiritual growth, worship, spiritual reflection, and seeking forgiveness and mercy from God (Allah).  Shab-e-Qadr provides an opportunity for Muslims to be close to Allah by worshipping (Ibadat), offering special prayer (Namaz), and repenting their sins from God (Allah). Thus, Muslims pray the whole night to seek blessings and believe that their sins and mistakes are forgiven, and prayers (namaz) are accepted on this holy night by Almighty Allah.

As per Shia Muslims, they believe that the Shab-e-Qadr may occur on the 19^th, 21^st, and 23^rd nights of Ramadan, with the 23^rd being the most important or holiest, or sacred night. As per Sunni Muslims, they believe that the Shab-e-Qadr may occur on odd-numbered nights and fall on the 21^st, 23^rd, 25^th,27^th, or 29th in the last ten days of Ramadan. This special night also allows Muslims to seek forgiveness, blessings, and rewards from Almighty Allah. God (Allah) grants forgiveness and opens the door of heaven on the special nights of Shab for those who regret their sins and seek blessings and rewards. Thus, Muslim individuals worship (Ibadat), offer special prayer (Namaz), and recite the Holy Quran on the night of Shab-e-Qadr to regret their mistakes and seek forgiveness, blessing, and rewards from Almighty Allah.

On this day, Muslims recite the verses from the Quran the whole night to celebrate this day. Special prayers and dua are also offered on this night to Allah. Muslims believe that the Shab-e-Qadr night comes with mercy and blessings of God, supplications are accepted, and sins are forgiven on that night. During the last 10 days and nights of Ramadan, some Muslims spend the most time in offering prayer (namaz) in the Mosque. Ramadan also allows for all the Muslim devotees to be saved from the Hellfire. In the holy month of Ramadan, a Muslim is also blessed with a night (Laila-tul-Qadr) that is better than a thousand months.

Muslims believe that the mercy, rewards, and blessings of God (Allah) are multiplied on the nights of Shab-e-Qadr. It is also believed that Allah grants more forgiveness on the nights of Shab-e-Qadr to those people who are seeking to regret their mistakes in their lives. As per Islamic Belief, the good deeds performed on the special or holiest nights of Shab-e-Qadr are more rewarded than on any other nights. Thus, Muslims must seek forgiveness, blessings, and rewards on the holiest nights of Shab-e-Qadr from Almighty Allah.
