The Night of Decree: Lailatul-Qadr

Whoever prays during the Night of Decree/ Lailatul-Qudar, with firm belief and expecting reward for it, his previous sins are forgiven,” -Bukhari and Muslim
When is the Night of Degree?
The Night of Decree is one of the odd nights of the last ten nights in Ramadan.
The Messenger of Allaah sallallaahu ‘alayhi wa sallam said, “I was informed (of the date of the Night of Decree) but I was caused to forget it (or I forgot); so, search for it in the odd nights of the last ten nights of the month of Ramadan.”  Reported by Muslim
Signs of Laylatul-Qadr: The Morning After Laylatul-Qadr
The Prophet sallallaahu ‘alayhi wa sallam, described the morning after Lailatul-Qadr, so that we may know when it occurred. The Prophet sallallaahu ‘alayhi wa sallam, said: “On the morning following Lailatui-Qadr the sun rises not having any rays, as if it were a brass dish, until it rises up.” -[Muslim, Abu Dawud, Tirmithi and Ibn Majah]

Allah (SWT) says in his noble Quran: “Verily, We sent it (the Quran) down in the night of Al-Qadr (Decree)* And what will make you know what The Night of Decree is? The Night of Decree is better than a thousand months. Therein descend the angles and the Ruh (Gabriel) by Allah’s permission with all Decrees (All that nights), there is peace (and  goodness from Allah to His believing slaves) until the appearance of dawn” [Al-Qadr:97]. Whoever is deprived of its good is really deprived (of something great).
