When Lailatul Qadr is equivalent to 1000 months (or more than 83 years!) of worship, being familiar with its signs is of great benefit.
It has been authentically narrated upon the authority of Jaabir ibn Abdullah (Radhiyallahu ‘Anhu) who said: the Messenger (saw) said:
“Indeed I was shown Lailatul Qadr then I was made to forget it. It is in the last ten nights (of Ramadhaan) and it is a bright night, neither hot or cold..in the version of Az Zayaadee it mentions concerning the brightness of the night: “..as though there is in it the type of moon that overpowers the stars (in brightness)..” then in both versions the messenger said: “Devils on that night will not be able to come out until fajr”
(Collected by Imaam ibn Khuzaima in his ‘Saheeh’ and declared ‘Saheeh’ by Shaikh Al albaani in ‘Saheeh ibn Khuzaima 2190)
When Ubay ibn Ka’b was asked on an occasion ‘what are its signs’ he responded by saying “its signs are the signs that the messengers (saw) informed us of. That the sun will rise the following morning having no rays”
(collected By Ibn Khuzaima in his ‘Saheeh’ and declared Hasan by itself and ‘Saheeh’ when supported by other than itself by shaikh Al albaani in saheeh ibn Khuzaima 2193)
and some narrations mention that it rises ‘like a bronze disc’
From the people of knowledge there are those who say that perhaps the reason for the sun rising without rays is the vast abundance of angels present on earth ascending into the heavens at fajr, obscuring the suns rays.
This is fortified by the statement of the messenger (saw) in the following hadeeth:
Upon the authority of Abu Huraira who said: “Lailatul Qadr is the 27th or the 29th night. Indeed the angels are more abundant upon the earth on that night then the number of stones (upon it).
(Saheeh Ibn Khuzaimah 2194 and declared ‘Saheeh’ by Shaikh Al Albaani)
Supplication on Lailatul Qadr
Upon the Authority of Aisha (Radhiyallahu ‘anhaa) who said:
“I asked:” Oh messenger of Allah! If i am granted success in ascertaining Lailatu Qadr what should i supplicate?
So he said: “You should say: “Oh Allah! Indeed you the one who pardons, you love to pardon, so pardon me” (Allahumma inaka ‘afoowun tuhibul afwa fa’fu ‘anee)
(Collected by Abu Dawood 3850 and declared: “Saheeh” By Shaikh Al Albaani)
Note: it should be noted that the wording انك عفو كريم… That is common is among the Muslims, the additional word كريم is not established upon the Messenger -Sallallahu alaihi was Salam
This version of the dua was declared ‘Dhaeef in Dhaeef Al Jaami’ (1175)
Shaikh Albaani mentioned in Silsiltul Ahaadeeth As Saheehah 3337 page 1011: “There occurs in the Sunan At Tirmidhi after the statement ‘Afuw’ the addition ‘Kareem’ this wording has no origin in any of the aforementioned sources (of hadeeth) neither is it present anywhere else from those who narrated from her (i.e. Aisha)..”
May Allah grant us success in finding it and establishing good upon it
