Laylatul Qadr is better than a thousand months
In the Holy Quran Allah (swt) says: “Indeed, We revealed [the Qur’an] during the Night of Decree. And what can make you know what is the Night of Decree? The Night of Decree is better than a thousand months. The angels and the Spirit descend therein by permission of their Lord for every matter. Peace it is until the emergence of dawn.” (97:1-5)
Previous sins will be forgiven
One who spends the night in prayer, his previous sins will be forgiven. Prophet Muhammad ﷺ said, “Whoever spends the nights of Ramadan in prayer out of faith and in the hope of reward, he will be forgiven his previous sins.”
Deprived is truly unfortunate
One who is deprived of Laylatul Qadr is truly unfortunate:
The companion Anas ibn Malik reported: “Ramadan approached, so the Messenger of God said: ‘This month has come to you, and in it there is a night that is better than a thousand months. Whoever is deprived of it is deprived of all goodness, and no one is deprived of its goodness except one who is truly deprived.”
When it occurs?
The majority of scholars are of the opinion that Laylatul-Qadr may occur on any of the odd nights in the last ten nights of Ramadan.
The Prophet Muhammad ﷺ said, “Search for Laylatul-Qadr in the odd nights of the last ten nights of Ramadan.”
What to do?
If one finds Laylatul Qadr he should seek forgiveness from Allah.
A’isha asked the Prophet, “O Messenger of Allah! If I knew which night is Laylatul-Qadr, what should I say during it?” And he instructed her to say:
اللَّهُمَّ إِنَّكَ عُفُوٌّ كَرِيمٌ تُحِبُّ الْعَفْوَ فَاعْفُ عَنِّي
O Allah! You are Most Forgiving, and you love to forgive. So forgive me.
If one cannot pray whole night
If anyone cannot spend all the odd nights of last ten days of Ramadan and is not able to pray the whole night he should at least pray Isha and Fajr in congregation on that night. It would be enough to fill its scales In Sha Allah. The Prophet ﷺ said: “Whoever attends Isha prayer in congregation, then he has the reward as if he had stood half of the night. And whoever prays Isha and Fajr in congregation, then he has the reward as if he had spent the entire night standing in prayer.”
Imam Malik (d. 179 H) narrated that he had heard that Said ibn al-Musayyab (d. 94 H) used to say, “Whoever is present at Isha on Laylatul-Qadr has taken his portion from it.”
