One of the most distinctive aspects of the month of Ramadhan is that it includes lailatul qadr (the night of power), which is the most blessed night of the year. This is that very night in which Allah Ta’ala chose to reveal the Holy Quran upon our beloved Rasool (s.a.w.). This is also the night wherein Allah decides the destiny, sustenance, birth, and death etc. for His creation. It is mentioned in the Holy Quran that this night is better than a thousand months (83 years & four months) as Allah himself speaks:
“The night of al qadr is better than a thousand months.” (verse 3 Surah Al Qadr).
This means the worship performed in this night brings more reward than that worship carried out for the period of a thousand ordinary months.
In the authentic teachings of Rasoolullah (s.a.w.), it is mentioned that Allah Ta’ala showers his special mercy in this night towards the inhabitants of the earth, accepts the duaas made by his servants and forgives all those people who repent sincerely, as Rasoolullah (s.a.w.) has stated in a hadith
“Whosoever stood up in front of Allah on the night of qadr with Iman and true conviction of attaining reward from Allah, in return, Allah will forgive all his previous sins.” (Muslim)
According to authentic sources lailatul qadr falls in any one of the last five odd nights of Ramadhan i.e. 21, 23, 25, 27 and 29th, as we are told in the hadith related by Ibne Umar (r.a.), Rasoolullah (s..a.w.) said “ ...and, search for lailatul qadr in the odd nights of the last ten days of Ramadhan.”
WHAT SHOULD BE DONE IN THIS NIGHT?
In this night a person should make worship of Allah Ta’ala exceptionally. One can engage in the offering of nafl (Sunnah) prayers as much as possible or in supplications, in the recitation of the Holy Quran or by any other good deed, which is not contrary to the Shariah.
“The person who deprives himself from the blessings of Lailatul qadr, indeed has deprived himself of all good and none other than an ignorant person is deprived from such good.” (Ibne Majah).
Considering this hadith, we should attempt to spare some time for the worship of Allah Ta’ala on this auspicious night.
The most profound way to derive benefit from the blessings of this night, is to stay awake for the whole night and spend it in prayers, but people who cannot do so, for any reason, should at least spare a reasonable portion of the night for Allah. Some rakaahs should be offered in the least, after midnight as tahajjud, the Quran should be recited, duaas be made, and any form of zhikr should be constantly uttered.
Once, the beloved wife Aiysha (r.a.) inquired from Rasoolullah (s.a.w.) as to what duaa should be made on the lailatul qadr, upon this Rasoolullah (s.a.w.) taught her the following duaa
"Allahumma innaka afuwwun kareemun tuhib-bul af-wa fa-afo anni"
(O Allah, You are the One who grants pardon for sins, loves forgiving, so forgive me.)
Indeed the blessings of our Lord are innumerable, but fortunate are those who reap them and regard them as significant.
Abu Mas'ud 'Uqba ibn 'Amr al-Ansari al-Badri reported that the Messenger of Allah, (PBUH), said, "Anyone who shows the way to something good has the same reward as the person who does it." [Muslim]
E.g. if you encourage someone to go for Salah, or pay Zakat and the person actually goes ahead and prays or pays Zakat, Allah will reward him for the good deeds and at the same time give you (the one that encouraged them to do good) an equal reward as he has given them- without decreasing what he gave them.
